Infineon Technologies AG has announced a single-chip solution for ADSL2+ broadband integrated access device (IAD) and home gateway applications enabling services such as VoIP, video-conferencing and IPTV.

According to Infineon, the new Danube chip features the industry's highest level of integration, allowing manufacturers of residential broadband IAD products to deliver systems supporting "triple-play" services using up to 60 percent fewer chips compared to competing solutions.

The Danube chip comprises an ADSL2/2+ transceiver, a 32bit MIPS CPU, a VoIP co-processor and two integrated codecs. Infineon said the chip's CPU power, hardware acceleration and integrated VoIP telephony enable it to support full 24Mbps ADSL2+ data rates for advanced media services, including IPTV, and provides headroom for additional applications.

The software suite provided as part of the complete reference design supports VoIP features such as three-way conferencing and caller ID and echo cancellation for high-quality voice. Multiple interfaces enable manufacturers to enhance systems by adding WLAN, Bluetooth, Ethernet switching, DECT, ISDN, video codecs and other features to complete the IAD design. The Danube chip also supports upcoming features of next-generation networks such as remote management functions, higher data rates through bonding mechanisms, and fixed-mobile network convergence.

In addition, said Infineon, the next-generation single-chip design of the Danube paves the way for cost-effective and flexible IAD solutions by meeting the system size reduction and high integration requirements of the CPE market.

"With Danube, we are integrating Infineon's market-proven ADSL2+ technology with the superb voice quality of our Vinetic VoIP product to offer a complete solution to meet the exploding demand for ADSL2+ and VoIP applications," said Christian Wolff, senior vice president of the Communication Solutions Business Group and general manager of the Wireline Access Business Unit at Infineon. "The open architecture and processing power of Danube make it easy for manufacturers to differentiate products through feature upgrades. This reduces the risk for investment dramatically."

Engineering samples of the Danube chip (PSB 507x2) will be available in August 2006, with production volumes scheduled for Q4 2006.
