SILICON LABORATORIES REPORTS STRONG FIRST QUARTER RESULTS

—Company Grows Revenue by 33 Percent and Expands Earnings and Operating Income—

AUSTIN, Texas — April 30, 2008 — Silicon Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance, analog-intensive, mixed-signal integrated circuits (ICs), today reported better than expected first quarter revenue of $98.2 million, a 33 percent increase over the same period last year. Earnings per share for the quarter exceeded guidance, and the company nearly tripled operating income compared to the same period last year.

Financial Results

The company delivered favorable results across the board during the first quarter. Revenue of $98.2 million exceeded guidance.  GAAP gross margin was 61.5 percent, GAAP operating income increased year-over-year to $11 million, and GAAP diluted earnings per share from continuing operations increased significantly compared to the same period last year to $0.21.

The following non-GAAP results exclude certain non-cash charges. Non-GAAP gross margin of 61.8 percent was at the high end of the corporate range of 60 to 62 percent. Operating expenses were slightly lower than expected, resulting in non-GAAP operating income of $21.3 million, or 21.7 percent of revenue, representing very strong operating performance relative to seasonal market trends. It also marks a near tripling of non-GAAP operating income from the same period last year. Non-GAAP diluted earnings per share from continuing operations was $0.38, representing a year-over-year increase of more than 100 percent. The reconciling charges are set forth in the financial measures table included below.

During the first quarter the company continued aggressive execution of its share repurchase program, completing repurchases totaling $137 million. The company ended the quarter with $467 million in cash, cash equivalents and investments.

Business Summary

Strong operating performance in the first quarter was coupled with a number of positive business drivers. A doubling of channel design wins for the broad-based products year-over-year, a strong quarter of new product announcements and the addition of new tier-one customers and design wins all offer strong indications of solid momentum in the business.

Broadcast revenue to handset customers increased sequentially in what is typically a seasonally weak quarter, demonstrating the strong competitive position of the company’s broadcast audio solutions. The company announced new products in both audio and video broadcast that further differentiate Silicon Labs from the competition. The continued adoption of the current portfolio, increasing attach rates and a record number of design wins, clearly demonstrated the strength and long-term potential of the business.

The MCU business was up almost 40 percent over the same quarter last year and down sequentially due to seasonal weakness primarily in the portable navigation market. Record development kit shipments, a high rate of design win activity and new product introductions continued throughout the quarter, including the introduction of the industry’s first 8-bit MCUs capable of operating with only a single cell battery. Healthy business trends are expected to drive the MCU product line to sequential revenue growth in the second quarter.

Demand for timing products and stable performance of the company’s foundation businesses also supported the strong results.

“We have a global business, a number of new product cycles and new tier-one customers beginning to ramp. We’re introducing products at an accelerated pace and continuing to fortify our leadership position in key markets,” said Necip Sayiner, president and chief executive officer

of Silicon Laboratories. “Together with strong operational performance and conservative financial management, we are delivering a combination of growth and profitability virtually unmatched in our sector.”

For the second quarter of 2008, the company is guiding revenue in the range of $98 to $101 million.
