PRESS RELEASE

Inphi Corporation Demonstrates First-Ever Commercial 50G Product Capabilities for Optical Communications

New optical components company to develop and sell high-speed indium phosphide chipsets at 40 Gbps, 50 Gbps and beyond

WESTLAKE VILLAGE, Calif., October 8, 2001 - Inphi Corporation, an emerging optical components company, today announced it has successfully developed and tested the world’s first commercial indium phosphide (InP) integrated circuits capable of network performance levels higher than 50 Gbps.

This product will position Inphi to deliver the industry’s highest bandwidth, lowest power OC-768 solutions and ultimately enable network service providers to offer customers the fastest fiber optic network transmission speeds available to date.

These high-speed integrated circuits based on InP demonstrate significantly superior performance at OC-768 levels and reinforce the value of InP as the leading technology for use in high-speed applications. Unlike more traditional materials such as silicon germanium (SiGe) and gallium arsenide (GaAs), which are used in many 10 Gbps designs, InP today is able to meet higher throughput demands of 40, 43, and 50 Gbps.

"In a very short period since the availability of our GCS InP HBT technology, Inphi has been able to achieve first pass success. Inphi’s modeling and design methodology yields circuits that maximize the performance of the GCS carbon-doped indium phosphide process technology," explained Chanh Nguyen, CTO of Global Communication Semiconductors. "The Inphi circuits are the most complex we have seen to date."

These circuits are Inphi’s first 4:1 multiplexer and 1:4 demultiplexer prototypes and operate at a data rate greater than 50 Gbps with a power consumption of less than 900

milliwatts. This breakthrough development will enable OC-768 chipsets to run at 40, 43, and 50 Gbps while operating at power levels comparable to those of today’s OC-192 chipsets.

"With their revolutionary indium phosphide design technology, Inphi is poised to lead the emerging OC-768 optical communications component industry," stated Dado Banatao, managing partner of Tallwood Venture Capital and Chairman of the Board at Inphi. "Inphi delivers the industry’s highest bandwidth components for multiple market segments. Network service providers have been clamoring for this level of performance for some time, and now we can give it to them."

"The optical communications industry has long suffered from a dearth of components from fiber to framers," said Allan Armstrong, Director of Optical Transport Semiconductors at RHK. "Inphi’s new indium phosphide circuits will pace the adoption of 40 Gbps technology and represent a significant accomplishment in indium phosphide."
