Thank you, Mitch. Good afternoon to all of you joining today. The Semtech team executed exceptionally well this quarter, delivering record revenue across our key focus areas, earnings leverage that continue to outpace revenue growth and significant progress on portfolio optimization. Revenue was $342 million, growing 33% year-over-year, and we delivered strong operating leverage with earnings per share of $0.71, growing 73% year-over-year, more than twice as fast as revenue growth. We are at the center of one of the most significant infrastructure build-outs in history, and our portfolio plays an essential role. We are well aligned with the ramp to 1.6T complementing 800-gig growth and demand signals that we are strengthening across every part of data center portfolio: copper, fiber and photonics. We expect this momentum to carry through the second half of the year and into fiscal 2028. We're also reshaping Semtech with purpose. The announced sale of our cellular module business is a significant step in our portfolio optimization, allowing us to more sharply focus on our core growth areas. We are growing in our focus areas, sharpening the portfolio and driving operating leverage with the same goal in mind, building a predictable high-margin and high-return business. Now let me move on a discussion to our end market. Infrastructure net sales were $124 million, up 25% sequentially and 69% year-over-year, driven by outstanding performance in our data center business. Data center revenue was a record $100 million, up 39% sequentially and 91% year-over-year, supported by continued strength in 800-gig, 1.6T CopperEdge and the start of our 1.6T FiberEdge ramp. Our FiberEdge TIA driver solutions remain in exceptionally strong demand, and we continue to deepen our engagement across all the leading hyperscalers. We are now designed into every module provider in our target markets. Several on a sole-source basis, a reflection of technology differentiation and the supply availability we bring across both fully retimed and linear architectures. We're also seeing increasing engagement from a broader array of customers on emerging technologies like NPO and XPO as the networking ecosystem looks to us to align and help define the next generation of high-density, low-power optical architectures in our shared technology road map. On CopperEdge, we believe our linear equalizer solutions are the de facto industry standard. CopperEdge products up to 1.6T are solutions that are ready for volume deployment. We are currently engaging across a number of hyperscalers in cable and onboard applications and in design-in phase at all bandwidth up to 3.2T, thanks to linear equalizers compelling advantage in link margin performance and power savings. Based on strong market demand and the design win momentum, we expect continued revenue growth of 1.6T portfolio with the FiberEdge expected to exceed 50% market share by the end of the fiscal year and the CopperEdge already taking the lion's share of the linear equalizer market. We have made excellent progress in our photonics portfolio, broadening our customer base in both gain chips and high-power CW lasers, addressing both high-speed transceivers and CPO scale-up applications. Feedback from customer evaluations of our high-power CW laser for coherent light and 1.6T transceiver applications has been very positive, citing differentiating over temperature performance and power efficiency. We expect revenue contribution of CW lasers for transceivers to start in the first half of fiscal 2028. We're also pleased to have brought onboard photodiode design resources headed by an industry leader, expanding our photonics portfolio to PD arrays in the near future. Our combined PD and TIA design team has already engaged with the key customers, and we expect to deliver co-optimized high-performance solutions. Our photonics portfolio now spans gain chips, high-power lasers, semiconductor optical amplifiers and high-speed photodiodes for scale-up, scale-out and scale across data center connectivity applications. With this expanded portfolio, we are positioned to develop new growth drivers and grow our content per transceiver from high single-digit dollars to high double-digit dollars as the industry transitions from 800 gig to 3.2T, cementing our position as a true solution provider. On our capacity expansion plan, our team executed very well, securing equipment deliveries for this fiscal year and acquiring clean room space to fulfill strong customer demand. In less than 6 months, we completed a series of photonic acquisitions, procured fab equipment, expanded clean room space and onboarded exceptional management and technical talent. We have established a solid foothold in the photonics space and set a path for strong future growth. Given record backlog we carry into the third quarter, we project a 45% sequential revenue growth in data center, representing approximately 160% growth over the same period last year. We expect accelerating year-over-year growth into fourth quarter and continued momentum throughout fiscal 2028. Now moving to our high-end consumer end market. Net sales for Q2 were $39 million, up 2% sequentially and down 5% year-over-year. Our TVS business grew sequentially and remains very resilient in light of memory constrained pressure across the industry. Revenue growth continued to benefit from our strong share at the premium brand handset manufacturers, where we are expanding our content per device. SurgeSwitch, our newest circuit protection solution, is opening a new layer of TVS opportunity, addressing a gap as rugged mobile devices and high-performance portable systems push towards more demanding power and reliability standards. Our PerSe capacitive sensor design win pipeline continues to grow in specific absorption rate, smart wearable and other consumer applications, expanding with the lead customers on a broadening range of applications. The combined capacitive and force sensing offerings elevate our value proposition, strengthen customer retention and are pulling through sensors and TVS sales within the same customer base. We expect our design win pipeline to support the long-term growth for this business. Now moving to our industrial end market. Q2 industrial net sales were $179 million, up 16% sequentially and up 25% year-over-year, driven by another record quarter for LoRa. LoRa-enabled net sales were $58 million, up 31% sequentially and up 58% year-over-year, another all-time record. Our LoRa Gen 4 platform with the LoRa Plus, other RF protocols continues to gain market traction, and we expect it will be a key driver for the future growth. Gen 4 also delivers dual band capability and expand data throughput to 2.6 megabit per second, while preserving the sensitivity, multi-protocol flexibility and ultra-low power consumption that defines the LoRa advantage. This feature set enables new class of Edge AI applications while maintaining the long battery life and extended reach that our customers depend on and opens up incremental application verticals within smart home and security. We also continue to see LoRaWAN expanding into new use cases. In public safety, sensors can now transmit high-fidelity audio for AI-based verification rather than simple alerts. And in industrial environment, our work with industry leaders demonstrates how LoRaWAN and Edge AI together enable predictive maintenance at a level of the detail that legacy low-power sensors could not support. Amazon Sidewalk continues to build momentum, following Ring's launch of a new line of LoRa-based sensors in the U.S., Sidewalk is now expanding internationally, starting with Canada and Mexico, with Europe, Australia and Japan expected to follow. This is a meaningful step towards mass-market consumer adoption at Amazon's scale. Together, our 3 pillars LoRaWAN for industrial and commercial deployments, LoRa Plus with multi-protocol flexibility for smart home and security and the Amazon Sidewalk for mass-market consumer applications continue to create a solid framework for growth. We project another all-time high for LoRa revenue in Q3 with a growth of about 15% sequentially, equating to year-over-year growth about 65%. Our IoT systems and connectivity business recorded Q2 net sales of $98 million, up 11% sequentially and year-over-year. Our AirLink routers saw strong new business activity across mission-critical applications, driven by growing engagement with the national carrier partners on 5G stand-alone network slicing. This momentum was reinforced by our RX400 and EX400 5G RedCap routers moving into full-scale production this quarter, with wins continue to convert into shipment across a broad range of customers. We also continue to invest in AirLink software platform to provide new security and device management capabilities. These capabilities are giving mission-critical customers greater visibility and control as they manage larger, more complex deployments, reflecting our broader commitment to software R&D as a way to deliver more capability and values to our customers over time. In summary, our second quarter results reflected significant progress in Semtech's transformation, including a strong winning culture. But to be clear, the progress we are making is just the foundation, not a finish line. Our priorities for fiscal 2027 remain the same and are straightforward. First, supporting our unprecedented backlog and growth opportunities, we are actively securing incremental capacity for fiscal 2028 and beyond. Second, intensifying R&D investment to support customer technology road maps in a rapidly advancing market and adding new growth drivers, specifically in solution offerings for lasers, photodiodes, drivers and TIAs for 3.2T coherent light, XPO, NPO and CPO applications. And third, continuing portfolio optimization. We see this as a continuous journey, and there is more work ahead of us as we reshape Semtech. This is such an exciting time for Semtech. The business is just starting to inflect and the opportunities ahead has never been more compelling. With that, I will turn the call over to Mark for additional details on our financial results and our third quarter outlook. Mark?

Thank you, Hong. For Q2, we recorded our 10th consecutive quarter of net sales growth with record net sales of $342 million, above the high end of our outlook range. Net sales grew 17% sequentially and 33% year-over-year. Reflective of leverage in our operating model, we reported adjusted diluted earnings per share of $0.71, which increased at over 2x the rate of net sales growth on both a sequential and year-over-year basis. Net sales trends by end market, reportable segment and geographic region are included in the accompanying earnings presentation. Adjusted gross margin was 54.5%, up 150 basis points sequentially and at the high end of our outlook. Total semiconductor products gross margin was 62.8%, up 210 basis points sequentially and above the high end of our outlook, reflecting particularly strong contribution from 1.6T FiberEdge and CopperEdge and continued growth from our LoRa portfolio. We announced the signing of a definitive agreement to divest our cellular module business, which is recorded as held for sale on the Q2 balance sheet. To facilitate comparability for our go-forward business, we added an adjusted gross margin disclosure in our earnings release and earnings presentation that excludes the held-for-sale business. Excluding the cellular module business, Q2 adjusted gross margin was 59.7% or 520 basis points above consolidated gross margin, reflecting the magnitude of the structural shift on top of the 150 basis points of sequential consolidated gross margin improvement. We expect to provide a gross margin outlook, including and excluding the cellular module business until the close of the divestiture, which is expected to occur in the fourth quarter of the current fiscal year. We also expect the transaction to be EPS neutral on a non-GAAP basis. Adjusted net operating expenses were $103 million, below the low end of our guidance range, reflecting timing of project-related expenses. Demonstrating the operating leverage in our business, a number of metrics were favorable to the high end of our guidance range, including adjusted operating income of $84 million, adjusted operating margin of 24.4%, adjusted EBITDA of $91 million and adjusted EBITDA margin of 26.6%. Reflective of capital structure changes, Semtech remained in a net interest income position in Q2. We recorded adjusted diluted earnings per share of $0.71, above the high end of our guidance range, up 39% sequentially and up 73% year-over-year. Operating cash flow for Q2 was $69 million, up 90% sequentially from $36 million and up 55% from $44 million a year ago. Free cash flow for Q2 was $61 million, up 119% sequentially from $28 million and up 48% from $42 million a year ago. CapEx was 2% of net sales and includes expenditures to grow fab capacity supporting gain chips and CW lasers. We expect CapEx to grow as a percentage of sales, but to remain manageable and generally be below 5% of net sales, though timing of construction and equipment delivery could increase this percentage slightly on a single quarter basis. Our Q2 ending cash and cash equivalents balance was $204 million, and the principal amount of debt was $503 million, and net leverage ratio was 1.1. Now turning to our outlook for the third quarter of fiscal year 2027. We currently expect net sales of $410 million, plus or minus $5 million, up 20% sequentially and up 54% year-over-year at the midpoint, with growth expected across each of our segments. We expect net sales from our infrastructure end market to increase sequentially with projected sequential data center growth of 45% or 160% year-over-year with continued strong contribution from our 800-gig portfolio and a meaningful ramp in 1.6T CopperEdge and FiberEdge. We expect net sales from our high-end consumer end market to increase, benefiting from seasonal trends, market share gain in our TVS products and contributions from our sensing portfolio. We expect net sales from our industrial end market to broadly grow with LoRa revenue increasing about 15% sequentially and 65% year-over-year. Based on expected product mix and net sales levels, we expect adjusted gross margin to be 58.3%, plus or minus 100 basis points. At the midpoint, this equates to an increase of 380 basis points sequentially and 530 basis points year-over-year. Our gross margin outlook, excluding the cellular module business, is expected to be 63.9% at the midpoint, an incremental 560 basis points from the midpoint of the consolidated adjusted gross margin outlook. Adjusted net operating expenses are expected to be $112 million, plus or minus $3 million. Included in this outlook is increased R&D spend to accelerate time to market on key data center projects, along with SG&A that declines as a percentage of revenue. We have demonstrated strong returns on our R&D investment and believe we remain prudent on SG&A spend. This results in consolidated adjusted operating margin at the midpoint of 31%, up 660 basis points sequentially and up 1,040 basis points year-over-year. Adjusted EBITDA is expected to be $134 million, plus or minus $4 million, resulting in adjusted EBITDA margin at the midpoint of 32.8%, up 620 basis points sequentially and up 930 basis points year-over-year. We expect adjusted interest and other expenses net to be approximately $0.5 million. We expect an adjusted normalized income tax rate of 18%, reflecting geographic mix of income. These amounts are expected to result in adjusted diluted earnings per share of $1.05, plus or minus $0.03, up 48% sequentially and up 119% year-over-year at the midpoint, more than 2x revenue growth based on an expected weighted average share count of 99 million shares. I look forward to providing our financial framework and multiyear outlook at our upcoming investor event on October 15. We expect the framework will highlight the operating leverage in our business model, namely increasing gross margin, reflecting strong contributions from data center and LoRa, operating margin that grows with scale and with disciplined spend in G&A helping to support R&D investment and a structural shift in margins following the cellular module divestiture, all of which are expected to support strong EPS, EBITDA and cash flow metrics. With that, I'll turn it back to Mitch.

Thank you, Mark. We can now turn the call back over to the operator for the question-and-answer session.

[Operator Instructions] Our first question is from Quinn Bolton with Needham & Company.

Congratulations on the strong results. Hong, you mentioned needing to go out and secure capacity for fiscal -- sorry, calendar 2028 and beyond. But the data center business, I think you guided up 160% year-on-year in the third fiscal quarter. It sounds like it accelerates in the fourth fiscal quarter. How are you feeling near term about capacity and your ability to support continued upside in the data center business? And then I've got a follow-on data center question.

We anticipated a very rapid data center revenue growth. We started about 1.5 years ago. And thanks to that work, we're able to have enough capacity in the near term to support the customer ramp and also some drop in orders. So that allow us to expand our market share. Now with the strong booking momentum and record backlog, we see the capacity we have secured may not be enough in supporting the FY '28, especially second half of FY '28. So working with our manufacturing partners, both for front end and back end, back end means the OSAT from testing to packaging and die separation testing, working with the manufacturing partner to increase the capacity. The great news is that we have the financial capability to work with our partners to jointly increase the capacity allocation to Semtech.

I guess maybe quickly, just Hong, does that -- would you anticipate that requiring wafer prepurchases or any kind of similar prepurchases of back-end capacity? And then my follow-on question was just it seems like there's growing discussion of NPO solutions across the ASIC landscape, and I think even at the largest GPU provider as we look into the next 12 to 24 months. Can you just give us a brief outline of how Semtech is positioned to support the NPO market as it develops?

Yes. Thank you. So yes, the increase of capacity for the back end is primarily increase the tester capacity by adding more testers and also getting additional manufacturing partners qualified to mitigate the potential geopolitical risk. On the front end, we have been working with a leading partner in increasing capacity. We are mobilizing all different ways in increasing the prepayment, the CapEx or some other means. But I think our goal are the same to bring additional capacity to support the growth. As for your question about NPO, yes, absolutely. That's a strong trend. The primary driver is to increase the bandwidth density. And as the data total capacity increased dramatically, while shoreline space is limited, they need to have the density, high-density packaging. We're going to be benefiting from that. We're currently engaging, I don't know, 10, 15 different programs with all the module manufacturers and some of them we directly tied to the end customers. So net-net, we're going to be benefiting from that. We are already a leading provider of TIA arrays and our laser arrays, especially the linearized version excellent as well. So I just talked about our initiative to start photodiode arrays and by co-optimization between TIAs and photodiode, and we're going to bring to our customers even better solutions. So it's a great opportunity for us that can be translated into a new growth driver for us in the future.

Our next question is from Rick Schafer with Oppenheimer & Company.

I'll add my congratulations to you guys. Great quarter and even better outlook. If I could, I'll just start with a quick one on LoRa. I mean the run rate there was barely $150 million just a year ago. I mean we heard your guide on that, Hong, I mean, that's close to $60 million a quarter now so well over the $150 million just in the last 12 months. So is 20% still the right bogey because I think you're going to be doing about 3x that growth in the third quarter?

We certainly matched the 20% ceiling with Q3. We're seeing sequential growth of 15%. Year-over-year will be translating into 65%. So that is certainly higher than 20%. And we benefited from now 3 pillars of growth, not just the traditional LoRaWAN in supporting the industrial and commercial applications, but also LoRa Plus in security and smart home, smart buildings. And now with the Amazon and Ring -- the Sidewalk and Ring's strong engagement and their plan to deploy internationally start from North America, expanding into Europe and Australia, we see that is going to be a strong growth driver as well. So I do expect year-over-year growth is going to be better than 20% going forward and it's sustainable.

And then if I could, I'd love to just get a little bit more color on HieFo. Obviously, you're investing in capacity there. I think you've talked about tripling that capacity by the end of the year. So I don't know if you could level set us on where we are in the process, if there's any sense of a design funnel or revenue funnel or anything you could share on that? And then as part of your answer, I'd be curious, I mean, folks are talking about CW laser channel densities really rising, right, going up. So I'm curious how much does that pull the need or create the need for higher density drivers and TIAs? And then if so, what does that do to the complexity and the barriers to entry there for your competition?

Yes. So first, we start with the HieFo acquisition. Certainly, we have been the proud owner of that asset for the last 5, 6 months. We have made tremendous progress in upgrade the line and also getting more wafer starts reaching out to the customers. And with Semtech behind the asset, the customer confidence level has improved dramatically. So we're not only with the 3 anchor customers increasing -- they are increasing the demand, but we are able to expand into other key customers on the gain chips. Now we have been, as I mentioned in the prepared remarks, sending high-power lasers to 5, 6 module manufacturers, they have been evaluating and really satisfied, really, very excited about our best power conversion efficiency in the beam performance, over temperature performance. Those are pretty ideal in having 1 CW laser split into 4 channels or 8 channels for high-bandwidth transceivers like 1.6T and 3.2T. We also have the product. We start sampling to customers on semiconductor optical amplifiers. That's almost like a gain chip. You get the push current through, you will get amplification. So that is the foundation we are using. And the capacity is limited, as I mentioned. We are going to be increasing capacity by bringing more testers in the back end first. Then for the fab capacity, we're just fortunate to be able to acquire an already fully facilitized fab in the close proximity to the current facility. So that allow us to increase the fab capacity by 3 to 4x by the end of the year. So we're on track for that. As for NPO, the high density, certainly, when you do the high density, the spacing between different elements is become smaller. When you go high speed at the crosstalk and all the other performance, the packaging need is different, it's representing another new set of challenges. That's why we expand not only from the FiberEdge to photonics that will allow us to do co-optimization to improve signal integrity. And definitely, the industry is welcoming our move, and we have increasing engagement with the module manufacturers and hyperscalers because of that expanded capability.

Our next question is from Sean O'Loughlin with TD Cowen.

I'll add my congratulations on obviously some really strong momentum across the business here. I wanted to start with just a quick -- just a high-level question on data center strength. Really strong outlook in the fourth quarter and talking about acceleration through the back half. But I think in your prepared remarks, both Hong and Mark, you both mentioned the CopperEdge in a high-volume ramp. I think that aligns with some of your past comments. But maybe you could just talk about how to think about the contributors to growth and how that aligns with some of your commentary on TIA share towards the end of this year on 1.6T?

Yes. Thank you, Sean, and that's a good question. So maybe I will use this opportunity to just review the progress we have made in expanding our portfolio in the data center play. So we certainly -- the recent investment community over-indexing on CopperEdge is because that's the first time, I think, the investment community paid attention to Semtech. Two years ago, we developed this redriver equalizer solution, which can be embedded in ACC cable to interconnect to adjacent racks. And so that continues to be a really de facto standard for the industry for 1.6T, 2.4T, 3.2T and going forward. Copper scale-up continues to gain momentum, especially linear equalizer onboard. So we got multiple engagement and some of them will reach the finish line in the near term. Second area, the FiberEdge, 2 years ago, 800 gig, we had a market share about 18%. So over the 2 years, we have grown the market share well over 50% for 800 gig. 1.6T is just inflecting. So 1.6T, as I said in the prepared remarks, we are expecting to exit this fiscal year by January with better than 50% of market share. So now you see the FiberEdge area, not only we are gaining shares, the volume has increased dramatically for 800 gig, for example, transceivers from 2 years ago, what, 20 million units a year to this year, probably 90 million units a year. We're gaining shares. We benefit from increased volume, and we are expanding the product offerings, 800 gig and 1.6T and drivers. The driver revenue is to come. We got a wonderful product in the evaluation will be contributing to the revenue very meaningfully. A few months ago, we acquired HieFo and marked the beginning of our journey into the photonic area, and we're going to be expanding and having meaningful play in that area as well. So now, I'd like to encourage everyone to look at the data center play for Semtech is not just the CopperEdge. CopperEdge will definitely be a significant part of the data center revenue. But think about the FiberEdge, the leading share of the TIA and drivers and photonics offering from gain chip to lasers to photodiode to SOAs. So we're going to be continue to expanding our portfolio to become a key player in this area.

Great. And just if I could ask a follow-up and get Mark into the party here. The gross margin expansion quarter-over-quarter is striking even if you're just looking at the consolidated and not isolating the held-for-sale business. Just wondering, I guess, question on how much of that can be thought of as mix? And if data center continues to stay at this percent of revenue, is that something we should expect -- levels that we should expect to continue? Or is there some onetime thing? And then maybe as part of that, just talk about the capacity expansion and we've heard some of your suppliers talk about what they're seeing on the pricing side and what's giving you confidence on the margin sustainability?

Yes, Sean, I can address that and try to address that. So the sale of the cellular module business, I expect will result in over 500 basis points of gross margin improvement. That's the structural change. That's a significant structural change that we see in our gross margin profile. And I provided some detail in my prepared remarks, but I think it's helpful to walk through those figures again. So from Q1 to Q2, our consolidated adjusted gross margins increased from 53% to 54.5%. That's 150 basis points largely on mix. Q2 adjusted gross margin, excluding modules, was 59.7%, which is an incremental 520 basis point increase. Then we move to our Q3 guide. Our consolidated adjusted gross margins are projected to increase from 54.5% to 58.3%, 380 basis point increase. And then on top of that, we had 560 basis points to arrive in adjusted gross margin guide, excluding the modules at 63.9%. So you have the 500 basis points plus gross margin improvement just based on the structural change. But the 150 basis points to 380 basis points, that's mix. I think a good starting point post divestiture is that 64% gross margin. And as you're seeing the mix change, I mean mix is quite a powerful driver for Semtech as 1.6T continues to inflect as LoRa continues strong growth and 800 gig maybe just to briefly address pricing, right? We're not really seeing price erosion to 800 gig. That all compounds into some very strong mix changes, which is that 150 to 380 basis points that we demonstrated in Q2 and Q3.

Our next question is from Christopher Rolland with Susquehanna.

So this was kind of asked, but maybe more simply, the data center guide or next quarter's guide driven by data center. What exactly are -- like, what did you not anticipate that is driving this? Is it the 1.6T cycle? Is it LPO? Is it really that TIA attach that you're talking about? Or is it CopperEdge? What kind of drove the marginal upside versus perhaps your expectations or even the Street's expectation, guys like me?

Yes. Chris, that's a good question. So if you look at the data center portfolio, we know 800 gig is going very well. We got a lion's share, and we continue the volume increase. We also know the CopperEdge 1.6T timing that has been largely on track and going with the schedule. If you say upside came from a little bit earlier inflection for 1.6T FiberEdge, we know we are in intense engagement with all module manufacturers, as I said, and their customers. So we were just not very sure about the qualification timing, and that's why we're a little conservative in guiding for Q2 at the time. Now we have all the backlog and the customers want parts tomorrow. So we definitely have a very high confidence and conviction for Q3 and Q4. So if you say what's different from a few months ago, I mean, it's just the qualification timing. When customers need a solution, they go out of the way, they accelerate the pace of new technology adoption. So that is -- I've seen that before, but this is really, in a way, it's unprecedented and from the hyperscalers to module manufacturers to the technology providers, component providers, we're working all together to accelerate that pace. Does that make sense?

Yes, that totally makes sense. And then perhaps a follow-up, just as you ramp, HieFo -- excuse me, and you have all these new products coming into this portfolio, and you talked about getting to high double-digit per transceiver content for you guys. Can you walk us through just a time frame of when you expect these products to ship in volume to the market, whether it's these high-power CW modules, photodiodes, SOAs or anything else that, that acquisition will be able to provide?

Yes. So Chris, we only get into this area, as I said, for 5 months or so. We certainly have a great plan and great ambition. Right now, the ongoing product shipping in volume is a gain chip, and we're going to be having the CW high-power CW lasers and SOA available for sampling and qualification from the customer side in a couple of months. And -- but the significant increase in content in optical transceivers, as we said before, is more like 3.2T because we see the ramp of the FiberEdge for 1.6T, that means the customers already wrapping up the qualification and getting ready for volume production. If they don't have a solution now, they'll probably be late. We wanted to catch the next wave, so that is 3.2T. And the good old high-power CW laser work still is the most needed for that application. By then, we wanted to make a photodiode available as well because when the data rate going higher than 200 gig, they need every bit of help from electronic component and photonic component. So the co-optimization allows us to provide a cross-reference design solution to customers. That is also very much needed for 3.2T. So to answer your question, really the significant content increase in one optical transceivers will be coincide with the 3.2T transceiver cut in.

Our next question is from Harsh Kumar with BMO Capital Markets.

Hong, Mark and Mitch, congratulations on a stellar quarter and stellar guide. I had a one multipart and then another follow-up. Hong, you talked about 3.2T being the catalyst for your products catching growth. Could you talk about what the timing for 3.2T is as you see it in the field? And then I want to push back on your commentary a little bit as well. You talked about your content going from high single to kind of high double digits -- but when I look at all that you have in the pipeline, photodetectors and gain chips and drivers, et cetera, I would think the content would be more than teens. Are you just being somewhat cautious here? Or is there any other reason for that commentary?

Harsh, first of all, thank you for initiating coverage, and we look forward to working with you with your new platform. So probably I confused you, just high double-digit means 80%, 90% instead of 18%, 19%. So that's the content we're talking about.

And 3.2T timing, Hong?

3.2T timing, I would say, probably in the 18 months or so, but I think the design window will start opening up at about in 12 months period of time. So then the early movers, they'll probably be 18 months from now, and -- but I think the meaningful deployment will start probably in 2 years. 1.6T, even 800 gig will have a really very healthy runway over the next 2 years.

And then for my follow-up, if I can ask you about ACC and LPO. The reason why I'm asking you, you're coming out as the clear leader in those 2 technologies. You talked about it, I think, a little bit more positively in this call -- can you help us still give an idea of what we should expect the growth rate to be, let's say, exiting this year or at some point in time next year, what can these 2 businesses do?

Yes. So the ACC, we definitely have the clear visibility with the leading hyperscalers. We are going to be having the volume deployment start from Q4. But right now, all the cable manufacturers are ordering and increasing quarter-over-quarter, but the inflection is going to be start from the Q4. Then in the meantime, we're seeing so many design activities of linear equalizer on board. So dynamics, we start understanding this emerging market better now. ACC adoption is more coincide with the new platform design. So they wouldn't be yanking out the AEC currently in use and to put in ACC. But the linear equalizers on board design is happening on the board level. So we got a lot of activities. We continue to be very bullish on that market. As for LPO, it's almost -- we had a meaningful revenue from Q1, and that has been increasing moderately. But that deployment really get the industry, give them the confidence of the linear architecture and it works really well. So that evolved into NPO and some form of CPO and then even the XPO is including the LPO form with a linear equalizer -- well, the linear architecture instead of retimed. So I think in the future, the LPO impact not only as a stand-alone transceiver, but also the proof of the concept, the proof of the technology getting incorporated in more integrated form factor like NPO.

Our next question is from Joe Moore with Morgan Stanley.

Congratulations. Can you talk about the strength in 800 gig? You talked about that persisting for a while. What's your visibility into that? I know 1.6T is the big ramp, but 800 seems quite strong. Can you talk about that dynamic a little bit?

Yes. So Joe, we enter into the year for 800 gig, the industry is forecasting 50 million transceiver units to be consumed. Now we are hearing the number of 80 million, 90 million. And we have a very healthy backlog for FiberEdge to support 800 gig. And that is a continue. And we're just getting -- picking into our new booking report this morning. So existing customers, they're increasing the demand, not decreasing. In the meantime, the 1.6T is just starting. And so the Q3 will be the first quarter for us to really have a pretty significant revenue, as I said, between 1.6T FiberEdge and 1.6T CopperEdge, we will have -- they will be surpassing 50% of total data center revenue. So 1.6T is gaining a lot of momentum and gaining momentum fast.

That's very helpful. And then can you just discuss like-for-like pricing? Are you seeing any changes really in any part of your business, but particularly on the optical side, any change in pricing there to note?

Yes. So pricing is very favorable. Typically, as I said before, you offer 2x performance, you may be able to get 100% premium in the beginning, but it settles at a lower level. But right now, availability is more important to the customers and then the pricing is almost -- there are no erosion to be expected in the near term and at least not for any orders we booked in the backlog. Our cost is increasing slightly, and we are able to, in most of the cases, work with the customers and pass along the cost to them. And -- but we are here to build a long-term relationship with our customers. We are very mindful and not being viewed as using the seller advantage to gouge our customers. So we're working with them in a partnership fashion, but we are able to pass along the cost increases. So that's why when Mark talked about the gross margin, we're expecting the trend to continue to grow because of favorable product mix and the new product, we have a higher gross margin.

Our next question is from Tore Svanberg with Stifel.

Congratulations on the record quarter. Hong, so you're going to be at $0.5 billion run rate in data center next quarter. I'm just curious as we sort of think about $1 billion in data center revenue, how should we think about the mix between FiberEdge, CopperEdge and all the new products that are coming online?

So that's probably the one we're going to be providing more details in our October Investor Day because we plan to get the different -- the TAM for the different applications and our market share so that you can have a more comprehensive view for multiyear model. I hope you can come to that event, sorry.

Sounds good. And as a follow-up and a similar question for Mark. So ex-modem, we'll be at 64% gross margin. How should we think about the margin contribution from some of the newer products like PD, CW lasers and so on and so forth? Are they going to be at that corporate average or perhaps even above?

They should be above. So all the areas that you just mentioned, CW lasers, especially, they're at a data center gross margin, which is accretive to that corporate gross margin average.

Next question is from Craig Ellis with B. Riley Securities.

Congratulations on the stellar performance. I wanted to look at the business through the 1.6T lens. So this sort of follows up on part of what you got to with Joe. But can you clarify what you're looking for as things get going in the third quarter as a percent of mix? And then, Hong, it sounds like we're starting stronger in FiberEdge and CopperEdge comes along. So how would mix evolve for 1.6T as a percent of total as we look out to next year?

So Craig, thank you for the question. In Q4 -- Q3, the 1.6T is already surpassing 50%. I can just only imagine that it's going to be continue to grow north of 50%. But 800 gig continues to be very strong, and we have the Tri-Edge legacy product continue to kick in very strong. So -- but the trend is going to be growing the percentage of 1.6T is going to be higher and higher.

Got it. And then I wanted to go back to your comments where you indicated that beyond the near-term 45% Q-on-Q growth for data center in the third quarter and the 160% year-on-year growth, we could see acceleration. And the comment on backlog just suggests that you've got tremendous visibility out into fiscal '28. Can you comment on where that would be relatively greater and what some of the interactions are like with customers that are booking out that far? Is it really just you becoming a lot more strategic to the road map? Or is it that supply sufficiency point? Just help us see what you're seeing.

Yes. Thank you, Craig. And that -- I think it's all of the above. You see our product performance is great, and we can provide availability and also we are providing excellent services. So that has been the key drivers for us to gain shares.

Our next question is from Cody Acree with The Benchmark Company.

Congrats on the progress. Hong, maybe just a follow-up on the last question. With the bookings and backlog accelerating here in the second half, any quick thoughts on what kind of -- how long into '28 does that backlog extend? And any thoughts on what kind of growth that might support next year?

So the backlog for the remaining of this fiscal year, I would say, for our target is all booked. And for the next year, we probably over 70% there. And -- but the momentum is so strong. So we are going out to get more capacity secured. And so far, I would say the visibility side for the next fiscal year, we feel very confident about it.

Do you think, Hong, that you have upside to -- with that capacity addition effort? Do you think there's room in the industry for you to secure more and to continue to service upside?

Yes, between 50% and 100%, there's room for that. And we definitely wanted to be able to provide our customers for the product they need.

And then lastly, you've had a lot of success with your lead hyperscalers for ACC. Any thoughts on the expansion beyond that lead hyperscaler? How broadly do you think this gets adopted? And maybe what are the -- some of the challenges left to full adoption? Is it interoperability, support or cable qualifications?

So yes, at this point, for them, the availability and interoperability, probably more important for them. We have not seen many activities in driving us to interrupt with other industry participants.

Any thoughts on breadth of adoption?

So it's going to be more -- with time, it's going to be broader, and we'll start with the leading one and there are multiple engagement is ongoing. Some of them is going to be reaching to the finish line. So I guess we're at the time, right? But I do encourage -- I know that we still have some in the queue, but come to our October 15 investors event. So we definitely wanted to provide very comprehensive information on our technology road map, differentiation, TAM or share and multiyear model. So that will help you to build a multiyear financial model for us.

Our last question is from Scott Searle with ROTH Capital Partners.

Congrats on the quarter and incredible outlook in terms of data center and LoRa. Data center has been covered pretty thoroughly. So maybe hopping over to LoRa for a second. Just in terms of -- could you calibrate us quickly, you've been moving away from the China mix. It had been down under 50%. I want to just have a better idea about how that was progressing in the July quarter. And looking at the growth that you've seen from the first quarter to guidance now in the third quarter, it's up 50%. How big is Amazon now factoring into that? Are they over a 10% customer and kind of stack ranking the guidance into the third quarter? Is that mostly Amazon? Is it LoRa Plus? Is it something else there that's really driving the outlook? And lastly, to follow up now on the IoT side of the equation with modules now on the path to be divested. Other elements have arguably, periodically been core and then noncore on the router gateway and the IoT platform front. I'm wondering what the current thoughts are in terms of their continued inclusion as a core portion of Semtech going forward?

Thank you, Scott. On LoRa, and the majority of the revenue is still LoRaWAN and LoRa Plus start kicking in, probably representing about 20% to 25% of the total revenue mix. And Sidewalk is still, at this point, is nominal and this year will probably be high single-digit, but again a lot of potential once we are able to piggyback into the consumer at Amazon scale. As for the portfolio optimization, as we mentioned, it's a continued journey. And so far, we like the portfolio we have after the divestiture, but we'll continue to evaluate additional optimization effort. But we are focused on getting the current deal to the finish line and so which lead to the closing of the sale of the cellular module business.

There are no further questions at this time. I'd like to hand the floor back over to Mitch Haws for any closing comments.

Thanks, Paul. That concludes today's call. We look forward to seeing you at various investor events during the quarter, including our Analyst Day on October 15. With that, good afternoon, everyone.

This concludes today's conference. You may disconnect your lines at this time. Thank you again for your participation.
