Centillium Delivers Groundbreaking VoIP-Enabled, High-Speed Broadband on a Single Chip.

FREMONT, Calif. -- Expanded Palladia 400 Family Offers First-Ever Integrated System-on-Chip Solution Converging Voice and Data over DSL 

Centillium Communications, Inc. (NASDAQ:CTLM), a leading provider of broadband access solutions, has scored yet another innovation success with the debut of its expanded Palladia 400 family of chipsets, which deliver the industry's first integrated Voice-over-IP (VoIP) solution for the ADSL market.

The Palladia 400 series delivers up to 50 Mbps downstream and 5.5 Mbps upstream, enabling service providers to deploy premium services such as Voice-over-IP, virtual private networks (VPNs), video-on-demand (VoD) and streaming media, with lower overall costs and faster time-to-market. Leveraging Centillium's technology leadership, the Palladia 400 family improves overall system functionality and performance, especially for those end-users desiring voice-enabled broadband. The result is a versatile chipset family that delivers high-speed broadband access with built-in VoIP capabilities to customers around the globe.

The Palladia 400-2P includes two voice channels and is created for home gateway applications, while the Palladia 400-4P with four channels of voice is optimized for high-end enterprises. The chipsets provide a superior solution for consumers demanding faster connectivity with more integrated features, such as VoIP. Centillium's field-tested architecture combines an ADSL2/2+/2++ modem, a high-performance 200MHz network processor, a 200MHz dedicated voice DSP, two RMII and a USB port plus a PCI interface which supports all of the new wireless technologies -- including 802.11g and 802.11n -- in one complete, cost-effective package.

"Voice-enabled broadband is a driving force for the global telecommunications business and also for multiple market segments where premium services such as triple-play and streaming media will enhance the consumer experience," said Steve Rago, principal analyst, networking and optical communications, and head of iSuppli's Broadband and Digital Home service. "Innovation from companies like Centillium, with its unique Palladia chipset family featuring integrated VoIP over DSL, translates into new, feature-rich service offerings for carriers that contribute to the acceleration of broadband deployment globally, both in the enterprise and residential arenas. I expect that VoIP over DSL will experience a CAGR of more than 70 percent over the next four years."

"Centillium's Palladia P400-2P and 4P combine ADSL2 and VoIP capabilities into a single chipset. This highly integrated product provides us with the high performance we need, at a price we can afford," said Eric Teissandier, CEO of BeWan, a European designer and manufacturer of telecommunication and network products. "The Palladia chipset is our platform of choice because of its versatility, advanced QoS features and integrated IPSec security engine."

The Palladia 400's network processor seamlessly executes various routing and security protocol stacks while the DSP controls voice compression, VAD, CNG, DTMF generation and extra voice processing activities. This innovative architecture is maximized for a variety of ADSL2/2+/2++ CPE and CO applications, including integrated access devices, set-top boxes and media gateways for the delivery of value-added content services.

"DeTeWe has chosen Centillium's Palladia 400 chipset for the next generation of OpenCom platforms for home and enterprise applications," said Thomas Wellhausen, CEO of Winfinity, the technology group of DeTeWe, a leading provider of technology and innovations for telecommunications, computing and network, security and automotive applications. "We selected Centillium's solution because it offers industry-leading integration of VoIP and DSL functionalities, enabling us to considerably lower costs and to expedite product delivery. The Palladia 400 also provides us with the ability to offer high-performance routing and advanced VPN services with its integrated IPSec and Packet Header Processor."

"Centillium continues to push the envelope when it comes to delivering innovative broadband access chipsets to the communications industry. The extension of the Palladia 400 family offers powerful options to equipment vendors to target market segments with the best features and cost objectives," said Kris Shankar, vice president, product line management for Centillium Communications.

Palladia 400 Chipset Features

--Interoperability: The Palladia 400 chipset has industry-leading interoperability, working with leading soft switches and certified by major VoIP service providers. The chipset works with Annexes A, B and C and is currently the only Annex B ADSL 2/2+ solution on the market.

--Performance: High-system-throughput mechanisms with hardware packet headers and IPSec encryption acceleration ensure high system performance for high-speed routers and video/VoIP applications.

--Integration: The highly-integrated solution combines an ADSL modem, network processor, hardware AES, DES, and 3DES encryption engine, voice DSP and software, PCI, USB and two Ethernet MACs together. This ADSL home gateway integrates up to four deep compression channels of VoIP and VPN.

--Meets Service Provider Cost/Performance Requirements: Patented Dual and Single Ended Line Testing (DELT/SELT) features enable service providers to perform remote diagnostics, troubleshooting and provisioning, eliminating maintenance and truck-roll costs. Along with low power consumption and on-chip power management, this reduces the overall operational expenses and increases profit margins for service providers.
