inSilicon's Certified USB 2.0 PHY is the Connectivity Choice For Oak Technology's Advanced Imaging

Launches inSilicon's USB 2 PHY Into Imaging and Printing Markets

San Jose, CA, March 11, 2002 - inSilicon Corporation (Nasdaq: INSN) -- a leading provider of communications semiconductor intellectual property (IP), announced today that Oak Technology, Inc. a leading provider of embedded solutions for optical-storage and digital-imaging markets, has integrated inSilicon's USB 2.0 PHY into its new OTI-4110 system-on-a-chip (SOC) solution for personal imaging and printing applications.

Oak Technology will integrate inSilicon's USB 2.0 PHY as an integrated part of their Quatro™ imaging SOC platform. Combining inSilicon's USB 2.0 PHY with Oak's advanced Quatro DSP core and an embedded ARM processor, the OTI-4110 provides OEMs with a fully programmable platform for implementing the feature set and associated image processing required across a range of products. The OTI-4110 performs all the control processing, image processing and communications processing required in a personal imaging or printing appliance.

"The new USB 2.0 high-speed interconnect standard is quickly becoming a must-have product feature in a rapidly growing market for personal imaging and printing appliances," said Roger Pennington, vice president of design engineering for Oak Technology's Imaging Group. He added, "Some SOC vendors have decided to initially support USB 2.0 via an external USB transceiver chip. We integrated inSilicon's USB 2.0 PHY into our Quatro imaging SOC platform and designed it into the OTI-4110 because of inSilicon's industry-leading track record in USB IP solutions. It will help provide us and our OEM customers a competitive edge in this market."

"Our USB 2 PHY is an ideal connectivity solution for Oak's new personal imaging and printing chip," said Barry Hoberman, chief executive officer of inSilicon Corporation. "Licensing this complex and difficult to implement technology enables Oak to get their innovative imaging SOC to market faster and provides their customers with a single-chip, digital imaging solution with the latest high-speed USB connectivity standard. The future revenue associated with this transaction and the market validation from customers like Oak serve to further enhance the market position for our growing mixed-signal business."

Certified by the USB Implementer's Forum, inSilicon's USB 2 PHY is a complete mixed-signal semiconductor IP solution designed for single-chip USB 2.0 integration in both peripheral and host applications. The USB 2 PHY integrates high-speed, mixed-signal, custom CMOS circuitry in compliance with the industry-standard UTMI Specification. USB 2 PHY technology supports the USB 2.0 480-Mbps protocol and data rate, and is backward compatible with the USB 1.1 legacy protocol at 1.5 and 12 Mbps.
