SAN JOSE, Calif.--(BUSINESS WIRE)--April 2, 2001

Key Product Development Milestone Achieved for Delivering

Faster Data Transmission and Greater Bandwidth

Silicon Access Networks, Inc., a leading pre-IPO network processor company, today announced the demonstration of its 1.2 Gbps Low-Voltage Differential Signaling (LVDS) interconnect technology for its iFlow(TM) family of network processors and coprocessors. This new LVDS interconnect capability enables high-speed, chip-to-chip communication, delivering faster data transfer and greater bandwidth up to 9.6 Gbps using a single 8-bit bus.

"The integration of high-speed LVDS interconnect technology into our iFlow platform is another key milestone toward our promise of delivering unmatched performance in the network processing arena," said Perry Constantine, president and CEO, Silicon Access Networks. "We are poised to help solve the most pressing issues for network equipment vendors today: keeping up with exploding bandwidth demands, providing deep packet-processing and traffic management, and delivering carrier-class reliability."

With LVDS capabilities at 1.2 Gbps (600 MHz per pin), Silicon Access Networks LVDS technology provides the bandwidth to launch four 144-bit search requests for minimum-sized Ethernet packets at 10 Gbps using a single 8-bit bus.

Silicon Access Networks is also in the process of verifying a 0.13 micron CMOS test chip that is targeting 1.6Gbps LVDS interconnect speeds. The LVDS technology is a fundamental building block for Silicon Access Networks and provides backwards compatibility with lower-speed, industry-standard LVDS interconnect solutions, such as the Optical Interworking Forum (OIF) SPI4.2 standard. This technology has been designed into Silicon Access Networks iFlow products in the form of SPI4.2-, SPI4.2, and SPI4.2+ interfaces that utilize 8-, 16-, and 32-bit bus widths. This technology allows Silicon Access Networks to develop products with 115 Gbps of external interconnect capability on a single chip while minimizing power consumption.

About iFlow(TM)

Silicon Access Networks' iFlow solutions provide deep-packet processing at the low power, high performance, and port density required by advanced Internet Protocol (IP) devices in MAN and WAN edges and WAN backbones. Silicon Access Networks' iFlow family of networking processors, coprocessors, and software are ideal for providing all aspects of advanced Quality of Service (QoS) provisioning and deep-packet classification with carrier-class reliability for next-generation IP products in service-provider networks.
