INTERSIL to acquire QUELLAN, creator of Q:ACTIVE® high performance analog signal processing technology

MILPITAS, CA, August 4, 2009 - Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog and mixed signal semiconductors, today announced that it has signed a definitive agreement to acquire Quellan, Inc., a privately held leader in the design of high performance analog signal processing integrated circuits (ICs). Quellan's innovative Q:ACTIVE® technology delivers unmatched signal integrity for improved system throughput and density with dramatically reduced power consumption.

Quellan, a Santa Clara, California company founded in 2000, utilizes a proprietary Collaborative Signal Processing (CSP) architecture to apply adaptive noise cancellation and equalization within the analog domain. This unique approach enables Quellan's ICs to address signal loss, dispersion, skew and noise in high-speed signal processing applications. Quellan's Q:ACTIVE technology will provide improved performance, smaller footprint and lower power solutions for communications and networking infrastructure, high-performance computing, storage and consumer electronics applications.

"The Quellan products and analog signal processing design expertise in driving high speed signals over long distances are a perfect fit for Intersil," said Dave Bell, Intersil's Chief Executive Officer. "Quellan's Q:ACTIVE technology is complementary to our video and DSL businesses, and we believe it will enable us to further penetrate new and existing high-margin markets."

Quellan's ICs are embedded inside active copper interconnects that dramatically improve the signal integrity, speed, density and distance of existing platforms, providing up to three times the signal reach of traditional passive cables. Quellan's noise-cancelling ICs can also reduce interference from various noise sources to achieve exceptional signal sensitivity for a wide range of devices.

"We are very excited to be part of the Intersil family," said Tony Stelliga, Quellan's Chairman and Chief Executive Officer. "Quellan's products are immediately applicable in many of Intersil's existing vertical markets, and we believe will create opportunities in new areas of the analog IC market," Stelliga said. The boards of directors of both companies have unanimously approved the merger. Intersil expects the acquisition will have an immaterial impact on revenue or earnings for the third quarter 2009 results.
