CENTILLIUM GETS MULTI-MILLION DOLLAR OPTICAL PROCESSOR ORDER.

Centillium Communications, Inc. (NASDAQ:CTLM), Fremont, Calif. has received a multi-million dollar order for one of its Mustang(TM) system-on-chip (SoC) processors from a leading manufacturer of broadband networking equipment in Japan for expected delivery within the next six months. This Mustang chipset will be utilized as the core processor for optical networking unit (ONU) devices at the customer premises for one of Japan's foremost telecommunications service providers. When fully deployed, the Mustang processor solution will power the high-bandwidth broadband access and next-generation network services in optical fiber-to-the-premises (FTTP) networks for hundreds of thousands of subscriber lines.

"The high-volume purchase is a testament to the tremendous levels of performance, integration, functionality and value this optical network processor delivers," said Didier Boivin, vice president of marketing at Centillium. "In terms of our optical business, this definitively put us on the map as a significant player in the fast-growing FTTP markets and positions us to deliver state-of-the-art optical products that can meet stringent performance requirements demanded by service providers."

This highly integrated, low-power Mustang solution enables the deployment of gigabit Ethernet passive optical networks (EPON) to the customer's premises for delivery of premium triple-play services such as bandwidth-intensive IPTV. Because it is fully interoperable with a variety of vendor solutions and supports a full range of protocols and relevant standards including IEEE 802.3ah, this Mustang product simplifies service provider deployments and ensures all data transmissions over EPON networks are bandwidth-efficient, error-free and low-latency. Centillium's end-to-end SoC optical solutions offer customers the highest levels of integration while minimizing bill-of-materials cost.
