Thank you, Emeka. Good afternoon, everyone. I will discuss our Q3 fiscal year '20 performance by end market and by product group, and then provide our outlook for Q4 fiscal year '20. In Q3 of fiscal year '20, net revenues increased 3% over the prior quarter to $141 million. We posted non-GAAP gross margin of 61.6% and non-GAAP earnings per diluted share of $0.41. In Q3 of FY '20, the enterprise computing market increased 16% sequentially, driven by a strong rebound in PON demand and represented 31% of total net revenues. The industrial market demand decreased 2% sequentially as growth from our LoRa business was offset by broad industrial weakness, and represented 34% of total net revenues. Net revenues from the high-end consumer market decreased 3% sequentially and represented 25% of total net revenues. Approximately 16% of high-end consumer net revenue was attributable to mobile devices, and approximately 9% was attributable to other consumer systems. Net revenues from the communications end market decreased 1% over the prior quarter and represented 10% of total net revenues.
I will now discuss the performance of each of our product groups. In Q3 of fiscal year '20, net revenues from our Signal Integrity Product Group increased 6% over the prior quarter, and represented 42% of total net revenues. Stronger demand from the hyperscale data center and PON segments were offset by weakness from the base station and broader industrial markets. In Q3, we made significant progress with our Tri-Edge PAM4 platform. Customer interest and activity is strong, as our Tri-Edge platform delivers low cost, low power and low-latency performance, ideal for emerging PAM4-based optical modules. At the recent European conference on optical communications, the interoperability and power savings of our Tri-Edge PAM4 platform was demonstrated. Our first Tri-Edge silicon is currently sampling and in system trials in 200-gig and 400-gig PAM4 applications with Tier 1 data center customers. We expect to have Tri-Edge production silicon in Q1 of fiscal year '21, and our first PAM4 production revenues in Q2 of fiscal year '21. We are very excited about the prospects for our analog PAM4 solutions. Our FiberEdge PMD platform also continued its positive momentum at PAM4 optical module customers. We recently announced our FiberEdge Linear EML driver, targeting 100-gig and 400-gig PAM4 optical modules. This product joins our 4 platform of linear TIAs that are currently shipping, which are also targeted at 100-gig and 400-gig PAM4 optical modules. Our FiberEdge products complement our Tri-Edge and ClearEdge CDR platforms, and we expect to see FiberEdge continue to ramp nicely in fiscal year '21.
In Q3 of fiscal year '20, our PON business, which is largely driven by China, rebounded strongly following a weak first half performance. We recently introduced our 10-gig XGSPON OLT chipset that is expected to be a key driver for next-generation PON deployments in China. The overall PON market demand is expected to improve next year as fiber to the home and enterprise deployments increased in conjunction with 5G infrastructure deployments. Semtech remains a PON PMD market leader, providing highly integrated solutions for 1-gig, 2.5-gig and 10-gig PON systems.
In Q3 of fiscal year '20, demand from the wireless base station market weakened slightly over Q2. While base station demand in FY '20 has been weak, we do expect both 4G and 5G deployments to be stronger in fiscal year '21. We believe our 5G market opportunity could triple versus 4G due to the higher 5G base station volumes and additional CDR content. Our current 5G front haul solutions are gaining good momentum, with several design wins at top-tier module suppliers. Our SIP product group recently announced its new Pro Audio/video chip platform, which is focused on transitioning the Pro AV industry from expensive proprietary equipment to standard 10 gigabit per second IP-based equipment, using software-defined video over Ethernet, or SDVoE . We believe this new chip platform will be a key enabler in driving the industry transition due to its lower power and cost. The primary target markets for our Pro AV business are enterprise, health care, and eSports infrastructure, and we expect our new chip platform to enable this business to grow significantly in fiscal year '21. The ever-increasing demand for higher data rates is driving greater demand for Semtech's Signal Integrity products. We expect this secular trend to continue, driven by the global expansion of hyperscale data centers, the global transition to 5G base stations, the acceleration of 10-gig PON and the emergence of software-defined video over Ethernet. We expect our SIP product group to benefit from this trend over the next several years, despite significant headwinds in the fiscal year.
For Q4 of fiscal year '20, we expect net revenues from our Signal Integrity Product Group to decline driven by broad-based weakness across all segments.
Moving on to our Protection Product Group. In Q3 of fiscal year '20, net revenues from our Protection Product Group were flat over the prior quarter, and represented 28% of total net revenues. Our protection business benefited from strength from our mobile business and increasing penetration of the industrial and automotive markets, while our broader consumer business softened. Demand for higher performance protection from the Automotive segment continues to grow as an increasing number of high-speed interfaces are deployed in new vehicles. Semtech devices targeted at Advanced Driver Assist systems, controller area network and local interconnect network interfaces, continue to see strong design win momentum. In addition, we are seeing strong design win momentum from all the leading smartphone manufacturers across the globe, with the exception of China smartphones, where our position continues to be negatively impacted by the Huawei brand. In Q4 of fiscal year '20, we expect our Protection business to be down slightly due to the customary end-of-year inventory reductions at our Korean smartphone customers.
Turning to our Wireless and Sensing Product Group. In Q3 of fiscal year '20, net revenues from our Wireless and Sensing Product Group increased 1% sequentially, led by growth in our LoRa business and represented 30% of total net revenues. The adoption of LoRa in numerous new IoT use cases across the globe, demonstrates tremendous value of LoRa in the fast emerging LPWAN market. In Q3, notable additions to the LoRa Alliance included Amazon, Intel and DISH, who are all respective leaders in their industries. Also in Q3, the wireless broadband alliance, together with the LoRa Alliance, released a joint white paper articulating numerous use cases that require both WiFi and LoRa WAN connectivity. The primary use cases included smart building, smart homes, smart city, smart transportation and smart asset tracking applications. We are already seeing new opportunities emerge globally, driving more WAN and WiFi functionality to be integrated into the same gateway, and we will comment on these opportunities and wins on future earnings calls. Some examples of recent LoRa use cases include Alibaba released its Beagle GPS-free tracker system based on LoRaWAN, that provides consistent geolocation data without GPS or cellular connectivity, simplifying deployment at very low-cost and power. Radio Bridge, an industry-leading supplier of IoT sensors, released its new LoRaWAN-based sensor platform. The Armored Sensor enables the tracking of accurate real-time data for a variety of industrial applications, including oil and gas, air quality and utility monitoring. Digimondo, a leading provider of secure IoT software solutions, announced a new end-to-end smart utility starter package based on LoRaWAN, which provides customers the software and hardware necessary to create smarter, more efficient and lower cost utility networks. IHM Pacific, a developer of IoT technologies for the smart Utility and Building segments, together with Andrea Informatique, developed a new LoRaWAN-based electricity metering solution for utilities and submetering use cases targeted at Asia and Europe.
And CAHORS Group, a leading solutions provide for smart energy grids, announced its new LoRaWAN-based Sentinel system that monitors faults and predicts failures in overhead voltage lines. In addition to these use cases, numerous other partners announced solutions targeting smart home, smart utility, smart agriculture and industrial IoT applications. Along with the increasing number of use cases, LoRa's momentum is also being underscored by the key LoRa metrics we track. Our key metrics update includes the number of countries with LoRa networks increased to more than 83 countries. By the end of fiscal year '20, we expect around 90 countries to have LoRa networks, which is up from 70 at the end of fiscal year '19. The number of public or private LoRa network operators increased in Q3 to approximately 123, and we now expect 133 LoRa network operators by the end of fiscal year '20, up from 101 at the end of fiscal year '19. The estimated number of LoRa gateways deployed increased to more than 500,000. These gateways will support approximately 2 billion connected end nodes. We expect the number of LoRa gateways deployed to exceed 550,000 by the end of fiscal year '20. The cumulative number of LoRa end nodes deployed increased to 117 million, and is trending to 135 million by the end of fiscal year '20. And the LoRa opportunity pipeline is now over $500 million, with an additional $200 million of leads feeding the opportunity pipeline. We anticipate that, on average, 40% to 50% of this pipeline will eventually convert to full deployment over a 24-month time line.
Our pipeline of opportunities remains geographically well balanced, with over 65% of the opportunities coming from the Americas and Europe, and includes a growing number of consumer use cases, where the volumes could be significantly higher and could move to deployment more rapidly than those use cases in the industrial markets. Several of these volume use cases moved out from fiscal year '20 to fiscal year '21, and as a result, we are expecting our LoRa-enabled revenues to end fiscal year '20, between $70 million and $80 million. We expect to exit the year at a quarterly run rate above the high end of this range.
Despite the weaker-than-anticipated fiscal year '20, based on a record LoRa POS in Q3, and the continued positive global adoption of LoRa, we still anticipate a 40% CAGR over the next 5 years, as LoRa becomes the de facto standard for LPWAN use cases, in what we expect to be a multibillion unit industry.
In Q3 of fiscal year '20, demand for our proximity sensing platforms was stable. While our Huawei smartphone business will continue to be a challenge, our proximity sensing business is benefiting from increasingly stringent global SAR regulations as health risks associated with increasingly powerful 5G radios become fully understood. Over the next few years, we expect the majority of smartphones and wearable devices shipped to North America and Europe to have SAR sensors included in their system designs.
For Q4 of fiscal year '20, we expect net revenues from our Wireless and Sensing Product Group to be down slightly, as stronger LoRa-enabled demand will be offset by broad-based market weakness. Moving on to new products and design wins. In Q3 of FY '20, we released 24 new products and achieved 2,381 new design wins. In Q3, our [ disti PoE ] POS also achieved a new record.
Now let me discuss our outlook for the fourth quarter of fiscal year '20. We are currently estimating Q4 net revenues to be between $130 million and $140 million. To attain the midpoint of our guidance range, or approximately $135 million, we needed net turns orders of approximately 35% at the beginning of Q4. We expect our Q4 non-GAAP earnings to be between $0.33 and $0.39 per diluted share. Our Q4 guidance assumes no further direct shipments to Huawei in this fiscal quarter.
I will now hand the call back to the operator. And Sandy, Emeka and I will be happy to answer any questions. Operator?
