Entropia(TM) III Shatters Internet Telephony Barriers Through Unprecedented Integration

FREMONT, Calif., April 21, 2003 -

Centillium Communications, innovator of broadband communications technology, today introduced Entropia III, its fourth generation voice-over-IP (VoIP) processor, the highest density, lowest power, and most cost-effective system-on-a-chip solution available on the market.

Integrating unprecedented digital signal processor (DSP) power and network processing resources, Entropia III supports more than 1,000 VoIP channels on a single chip while concurrently supplying carrier-class echo cancellation and a comprehensive set of telephony features. Such a high level of integration and chip density enables system vendors to achieve the maximum density solution for highly scaleable gateway designs.

"Entropia III is an extremely powerful VoIP processor that is a generation beyond any competitive solution on the market," said Fima Vaisman, vice president VoP marketing for Centillium.

Entropia III also shatters previous performance and power records by providing 28 GMACs of DSP processing and 1 GOP of network processing at under 3 milliwatts per channel for a complete solution. Such breakthroughs in performance and power efficiency represent a major leap forward in communication systems design enabling system vendors to meet mainstream needs of the VoIP market with highly scalable, efficient and low-cost systems.

"Centillium's Entropia III raises the bar for on-chip processing performance in VoIP infrastructure applications," said Gerry Kaufhold, Principal Analyst at In-Stat/MDR. "The industry will benefit because VoIP is becoming cost-competitive with TDM."

Entropia III's hardware acceleration, TDM cross-connects, and multiple packet interfaces are embedded into the solution to reduce board component count, provide flexibility and offer significant savings. Integration of DSPs and network processing on the same chip offers improvement in delay optimization, a key factor in achieving carrier-class voice quality.

A comprehensive suite of vocoders and concurrent support for VoIP over Ethernet and AAL5, as well as VoATM AAL1 and AAL2, highlight the rich feature set and flexibility that system vendors require to migrate to next generation wireline and wireless networks.

For Centillium's existing customers, Entropia III offers a comprehensive programmable high-level application program interface (API) that maintains backward compatibility to previous APIs and enables easy migration from previous Entropia solutions to the new platform.
