Original Press Release:

Centillium Combines Chipset Technologies to Propel Arion(TM) II Gateway CPE for Residential, SOHO Triple-Play Devices

Union of powerful, market-validated technologies for VDSL2 and VoIP yields exceptional performance, consumer experience

FREMONT, Calif., June 12 -- Centillium Communications, Inc. (NASDAQ:CTLM) today released Arion(TM) II Gateway CPE. The company's first gateway system-on-chip (SoC) for VDSL2 networks offers equipment manufacturers fast time-to-market and proven processing power for voice, data and video in residential and small-office markets. Arion II Gateway CPE integrates within a single device the features of Centillium's award-winning Atlanta 100 Voice over Internet Protocol (VoIP) system and its Arion eXtremeVDSL2(TM) digital device. The chipset also adds new, patented technology to boost service quality for demanding triple-play applications.

"We're pleased to introduce Arion II Gateway CPE as a solution that not only combines two premier technologies, but integrates our many years of experience in deploying VoIP network processors and DSL solutions worldwide," said Didier Boivin, vice president of marketing, Centillium. "And while its seamless interoperability, quick time-to-market and favorable cost-performance will distinguish Arion II Gateway CPE for our ODM and OEM customers, we believe the market will also recognize considerable value in the exceptional provisions for quality of service (QoS) and security we've built into this solution."

For Centillium, Arion II Gateway CPE culminates a history of successful product development across multiple broadband segments. A complete system solution, the chipset drives market-proven VoIP and VDSL2 technologies through a single software platform and includes comprehensive reference designs, promising low bill-of-materials costs and accelerated time-to-market. For IAD applications, Arion II Gateway CPE powers premium triple-play services including IPTV, VoIP and high-speed Internet by providing a fully featured gateway-on-chip solution for secure network routing, high-quality voice processing, robust video capabilities and high-performance data exchange over VDSL2 networks, with symmetric data rates up to 100 Mbps.

"VDSL2 is a key technology for delivering premium communications services to consumers," noted Joseph Byrne, an analyst with The Linley Group and author of A Guide to Gateway Processors. "A highly integrated gateway SoC, such as Centillium's Arion II Gateway chipset, that combines VDSL2 modem functions with VoIP and QoS capabilities enables CPE to deliver these services more effectively and at lower cost than the multi-chip approaches deployed today."

Arion II Gateway CPE supports full backward compatibility with ADSL2/2+ and VDSL infrastructure. The chipset includes a digital chip with integrated MIPS processor, encryption and QoS packet engines, a voice DSP, and an analog front-end chip. Furthermore, the chipset is accompanied with a robust software package and reference design that can be used right out of the box to build a production-ready VDSL2 IAD. This alleviates the need for systems vendors to develop customized software, leading to significantly lower development cost and an accelerated time to market.

Enhancing Quality of Experience

Compared to ADSL, the ultra-wide bandwidth of VDSL makes it significantly more susceptible to degradation of service quality due to crosstalk. Placing an even greater premium on QoS is the data integrity demanded by triple-play applications such as streaming video. To meet this challenge, Centillium developed the Crosstalk Rate Adaptation(TM) (XRA) technology, integrating proprietary, intelligent algorithms to eliminate line-drops and assure optimum data rates under crosstalk noise conditions. Arion II CPE and Arion II Gateway CPE products are the first Centillium SoCs to apply this advanced approach to enhancing the user experience; in addition, these chipsets employ Centillium's proven QoS packet engine, dedicated to assuring maximum quality of experience for voice and other network communications.


The Arion II Gateway CPE SoC solution is available today and includes software, full documentation and comprehensive reference designs for minimized time to market. Additional technical details and specifications can be found at
