SAN DIEGO and SAN JOSE, California — September 7, 2011 — Integrated Device Technology, Inc.

“This transaction enables IDT to intensify our focus on our core timing, interface and analog-intensive mixed-signal solutions for growing applications in cloud computing, wireless infrastructure and consumer mobility. In addition, it enables a new working relationship with Qualcomm,” said Dr. Ted Tewksbury, president and chief executive officer at Integrated Device Technology. “Working with Qualcomm gives us the opportunity to expand our business in next-generation smart media devices, and puts us in a stronger position to solve complex system-level problems by offering our customers tighter integration and increased performance.”

“Hollywood Quality Video is a well-recognized, award-winning technology that provides Qualcomm with a leadership position in the video processing space,” said Steve Mollenkopf, executive vice president and group president, Qualcomm. “Media consumption continues to cross device boundaries and create growing expectations for high-quality viewing experiences. When combined with Qualcomm’s high-performance Snapdragon processor, integrated HQV technology will raise the quality bar for media consumption on smartphones, tablets and other smart media devices.
