Thank you, Austin. Earlier this week, Silicon Labs accomplished a major milestone closing the divestiture of our infrastructure and automotive business to Skyworks Solutions for $2.75 billion in an all-cash transaction. The proceeds of which have been fully funded. We expect that net proceeds after taxes and fees to be approximately $2.3 billion. We are evaluating the best ways to return the majority of this capital to our shareholders while preserving an appropriate level of liquidity and financial flexibility for the business. The completion of this strategic transaction solidifies Silicon Labs as a pure-play leader in secure, intelligent, wireless connectivity for the IoT. Our team is now hyper-focused on helping customers use our integrated hardware and software development platform, an award-winning security technology to create connected devices for a wide range of industrial, commercial, home, health and safety applications. We're also working diligently to enhance production. Like the entire semiconductor industry, our supply chain conditions are tight. Yet even in this unprecedented operational environment, I'm pleased to share that Silicon Labs ended the second quarter on a strong note. Revenue on a total company basis exceeded the top-end of our guidance range at $278 million. IoT revenue ended at a new record high of $169 million, up 7% sequentially and 48% year-on-year. We also experienced another strong quarter of bookings exceeding $400 million for the total company and bringing our total for the last nine months to more than $1 billion. These successes in large part are due to strong demand for our wireless connectivity solutions. Our wireless product portfolio, which is unparalleled in breadth and depth, continues to see surging momentum, posting greater than 60% year-on-year growth in the second quarter revenue. We are also seeing strong top-line organic growth across all supported wireless protocols, including Bluetooth, Thread, Zigbee, Proprietary, and Z-wave. Additionally, we are rapidly growing our WiFi business as we have fully integrated the technology and teams from last year's Redpine Signals acquisition. The diversity of our business continues to factor into our success beyond just the number of wireless protocols we support. This quarter for our continuing operations we sold solutions to more than 20,000 customers across thousands of different applications. Our top 10 customers represented only 20% of our business. Design win lifetime revenue achievement grew 25% year-on-year reaching an all time high. I will now break out the business results in greater detail. Moving forward, Silicon Labs will report revenue from the divestiture business as discontinued operations and from IoT as continuing operations. Non-GAAP gross margin for the IoT business was approximately 57% in line with our model. During the June quarter, we implemented price increases in response to higher costs and expedite charges because of the current supply chain situation. We are working collaboratively with our customer base on pricing to ensure that while we recovered the impact of cost increases, we are at the same time preserving our relationships and superior track record of customer service. Our non-GAAP gross margin continues to represent a premium relative to competitors as our customers recognize our differentiation, innovation and value in multiple connectivity technologies, security and system design. Operating expenses for continuing operations were $85 million in Q2 with R&D expenses at $51 million and SG&A expenses at $34 million. Total operating expenses increased about $1 million in the quarter due to higher variable compensation based on upside business performance. Non-GAAP operating income on our continuing operations was $11 million or 6.6% of revenue for the quarter. On the now divested I&A business, Q2 was also strong resulting in $41 million in non-GAAP after tax income from discontinued operations. Overall for Silicon Labs encompassing both business units, we have the following quarterly results. Non-GAAP effective tax rate was 10.2% and non-GAAP earnings were $1.05 per share, which was above our guidance range. On a GAAP basis, operating expenses were $133 million, stock compensation expense was $14 million and amortization of intangible assets was $12 million. We had a GAAP operating loss of $11 million from continuing operations and $38 million in GAAP after-tax income from discontinued operations. GAAP net income was $20 million, or $0.44 per share, which was also above our guidance range. Let's now turn to the balance sheet. We ended the quarter with $622 million in cash and investments. Driven by solid performance and strong collections, the operating cash flow from continuing and discontinued operations year-to-date was $78 million. Accounts receivable was $100 million with DSO of 32 days, which is standard and we maintained a $400 million credit facility with no outstanding balance and our convertible notes, which have a par value of $535 million and mature in 2025 remain with our continuing operations. Finally, we have no known bad debts issues. Diving deeper into just IoT, we ended the quarter at $52 million in inventory, which represents inventory churns of 5.6 times, a number above our targets. As we enable more supply, we expect to churns to revert to a level of approximately 3 to 4 times. For our continuing operations, the mix of distribution business was 81% and distribution inventory increased four days, quarter-over-quarter to 50 days, which is typical. We expect channel partners to continue to play a strong role in our growth as a wireless leader. Now I'll cover guidance for Q3 2021. For continuing operations we expect the following: IoT revenue up from Q2 to a range of $170 million to $180 million. Non-GAAP gross margins to be in the range of 57% to 58%. Non-GAAP operating expenses to increase to about $93 million aligned to our goals of expanding our IoT platform, portfolio and team. We also expect a non-GAAP effective tax rate of about 14% and total non-GAAP earnings in the range $0.10 to $0.20 per share. On a GAAP basis from continuing operations, we expect gross margin to be in the range of 57% to 57.5%. Operating expenses to be approximately $116 million. Our GAAP effective tax rate to be about negative 11% and GAAP earnings per share to be in the range of $0.56 to $0.46 loss. Finally, we expect to report a one-time gain from the divestiture of approximately $2.1 billion, which will be reported in discontinued operations. And now I would like CEO, Tyson Tuttle to provide greater detail on the IoT business.
