Infineon Technologies Demonstrates 4-band Plan 998 VDSL Modem Solution for Access Network Systems and Next Generation Digital Loop Carriers Systems at CeBIT

Mar 22, 2001 | Market News

CeBIT, Hanover, Germany – March 22, 2001 – Infineon Technologies (FSE/NYSE: IFX), one of the world’s leading providers of Communications Integrated Circuits and a world leader and innovator in VDSL(Very high bit rate DSL) technology, today unveiled at CeBIT, its 4-band plan 998 VDSL modem solution, targeted at both ETSI and ANSI applications. The new 4-band VDSL platform will enable service providers to measure and evaluate the expected performance of the recently standardized 4-band VDSL modem technology.

The new 4-band VDSL solution supports both symmetrical 13Mbps (997) and asymmetrical 26/3 Mbps (998) spectral band allocation schemes, delivering data for distances of up to 1.5km over existing copper wire infrastructure. Standard VDSL is expected to resolve the bottleneck of current network bandwidth limitation of the existing DSL and cable technologies allowing new range of services and broadband application, which were until now out of reach. According to IMS, the overall broadband market for the DSL and cable technology is expected to reach over 77.0 million lines annually by 2005.

“The recently approved ETSI standard for VDSL prompted the carriers to search for a standard based broadband access solution to meet not only with the growing demand for fast Internet access but also the demand for high quality media streaming services to the office and home”, said Shlomo Berkovitz, General Manager of Infineon’s Broadband Access Business Group. “The Infineon 4-band VDSL solution is the product of vast experience gained in extensive VDSL field trials and deployment of our leading Ethernet over VDSL technology. When combined with a high level of integration and an integrated link state machine controller, the development of all VDSL local loop access elements, be it CPEs (Customer Premises Equipment) or DSLAMs (DSL Access Multiplexer) is made significantly smoother and shorter”, he added.

About VDSL Technology

The Infineon VDSL chipset is optimized for both CPE and DSLAM applications using the most advanced in-house IC manufacturing technologies. High level of integration is provided on the analog as well as on the digital chip. With all the necessary functionality integrated within the chips, the number of required external components is minimized for overall low system cost and complexity.

The digital chip with its integrated controller, embedded interleaver memory and flexible software allows operation of the modem as a stand-alone VDSL PHY. Highly integrated analog chip includes all-in-one necessary circuitry such as anti-aliasing filters, gain amplifier, DCXO, A/D and D/A. All necessary controllers are integrated into the digital chip (such as AGC, Blind Time Recovery and Channel Equalization).

Demonstration modules that implement VDSL spectral plan 998 are available now. Volume shipments are expected in Q3 of 2001.
