First to provide total timing solution based on both quartz and silicon, resulting in optimal cost and performance for the customer

SAN JOSE, Calif. – August 27, 2007 – Pericom Semiconductor Corporation (NASDAQ: PSEM) a worldwide preferred supplier of interconnect solutions used for switching, timing, bridging, and conditioning of high-speed serial signals, today announced the formation of SaRonix-eCera, a wholly-owned subsidiary merging two originally separate Pericom subsidiaries into one wholly owned subsidiary. The new entity will operate as a business unit within Pericom, closely aligned with the other Pericom product groups. SaRonix-eCera will provide leading edge frequency control product solutions for customers in networking, storage, wireless, computing and consumer applications.

“SaRonix-eCera’s unique vertical integration will result in cost-effective, high performance solutions and streamlined product development and manufacturing cycles for our customers,” said Alex Hui, chairman, president and CEO of Pericom Semiconductor. “The synergy provides customers with the industry’s most unique timing solutions that can be based on quarts, silicon, or a combination of both. And they have the additional benefit of obtaining their complete timing solutions from once source.”

“SaRonix-eCera offers high volume, very small surface mount frequency control products, world-class manufacturing capability ensuring quality products and is complemented by IC and crystal design teams in US, China and Taiwan,” said Lou Chang, president of the SaRonix-eCera subsidiary. “By combining the two entities, we offer more advanced and cost competitive industry timing solutions to our customers.”
