SILICON LABORATORIES ADDS INDEPENDENT DIRECTORS TO BOARD

AUSTIN, Texas — Sept. 10, 2007 — Silicon Laboratories Inc. (Nasdaq:SLAB), a leader in high-performance, analog-intensive mixed-signal ICs, announced today that Nelson C. Chan and Kristen M. Onken have been appointed to the company’s Board of Directors.  Both new directors bring valuable expertise to the Board and further expand the number of outside directors on the Board.

Mr. Chan is currently president and chief executive officer of Magellan, a leading maker of GPS devices for consumer and professional applications. His 25 year career includes experience in semiconductors, systems and consumer electronics. Mr. Chan spent 15 years at SanDisk as it grew to over $4 billion in revenue, eventually running the company’s consumer business as executive vice president and general manager. Mr. Chan’s leadership of rapidly growing businesses in highly competitive markets along with his insight into key industry segments and geographies align well with Silicon Laboratories’ emerging business opportunities.

Ms. Onken recently retired as CFO from Logitech, a multi-billion dollar maker of electronics peripherals. Ms. Onken’s 35 year career includes senior finance roles at Fujitsu PC and Sun Microsystems. She currently serves on the Board of Directors for Singapore-based Biosensors International. Ms. Onken’s experience managing financial and administrative functions at large multi-national companies and her background in corporate governance and Board committee leadership make her an ideal fit for Silicon Laboratories’ Board of Directors.

“I enthusiastically welcome to our Board Kris and Nelson whose track records and varied experience will be instrumental in our effort to build a diversified and highly profitable business,” said Necip Sayiner, president and chief executive officer of Silicon Laboratories.
