Infineon Takes DSL to the Next Level: Introduces Industry's First Fully Standard Compliant VDSL2/ADSL2+ End-to-End Solution

Munich, Germany - May 27, 2005 - Infineon Technologies AG (FSE/NYSE: IFX), a leading supplier of communication ICs, today announced that it is extending its comprehensive DSL-portfolio with VINAX™, a complete VDSL2/ADSL2+ end-to-end solution. VINAX is the industry’s first chipset that is fully compliant to VDSL2/ G.993.2 (Very-High-Bit-Rate Digital Subscriber Line 2), a standard consented earlier today by the International Telecommunications Union (ITU). VDSL2 is a key enabling technology for Triple Play services such as multi-channel HDTV, on-line/on-demand gaming and video applications, VoIP and high-speed Internet access. Leveraging the full VDSL2 frequen-cy spectrum of up to 30 MHz, VINAX drives symmetric 100Mbit/s over copper wires at distances greater than 350 meters (1150 ft), doubling the loop reach performance of existing VDSL solutions. VINAX’s flexible VDSL2/ ADSL2+ architecture allows system manufacturers to cover worldwide market requirements for broadband access with a single hardware platform, enabling global mass deployment of Triple Play services.

“We are very proud to introduce the industry’s first fully standard compliant VDSL2 chipset,” said Christian Wolff, Vice President Communications Business Group and General Manager Wireline Access Business Unit at Infineon. “Full standard compliancy is a prerequisite for interoperability and therefore the key enabling factor for mass deployment. Taking advantage of Infineon’s expertise in ADSL2+ technology with more than 6 million ports shipped in 2004 alone, VINAX assures highest ADSL2+ backwards compatibility and interoperability necessary for a smooth VDSL2 deployment. VINAX allows carriers to seamlessly upgrade their DSL networks by gradually changing line cards in the central offices or street cabinets to VDSL2 while end users still use their ADSL/2/2+ modems at home.”

The new VDSL2 standard combines three characteristics that are a precondition for successful mass deployment: enhanced, ADSL-like, long range loop reach performance, ultra high data rates over short loops and sophisticated Quality-Of-Service features like Dual Latency, Dual Interleaving, or Pre-Emption. Only the combination of all three factors enables the large scale roll-out of Triple Play services meeting end customer quality expectations for undisturbed video transmission and carrier grade Voice-Over-IP (VoIP).

"We are delighted to see standardized VDSL2 technology entering the market so quickly as it is a key element of next generation DSL business," said Tom Starr, Board Member of the international DSL Forum. "VDSL2 offers a combination of higher access bit-rates, enhanced QoS control, and ADSL-like long reach performance making it highly suitable for the quickly evolving telecom environment and allowing operators and service providers to reap higher revenues from emerging Triple-Play services, especially video over DSL"

According to a report from the market research firm In-Stat/MDR from November 2004 total revenue from VDSL ICs is expected to reach 440 million US-Dollar by 2008, representing an annual shipment of nearly 70 million ports - up from about 117 million US-Dollar revenues and 12 million ports shipped in 2004.

VDSL2 - the ultimate DSL-technology

The new transmission standard VDSL2 (G.993.2), recently consented to by the ITU-T, is solely based on DMT (Discrete Multi-tone Modulation) technology. It provides the long-reach capabilities of the ADSL2+ technology while enhancing the high data rates of VDSL from 70/30 Mbit/s to symmetric 100 Mbit/s. In order to carry such high bit rates within a reach of up to 350 meters the VDSL2 frequency spectrum has been increased from 12 MHz to 30 MHz. To meet carrier access market requirements for medium and long loops the transmit power has been raised up to 20 dBm and echo cancelling techniques were specified to allow ADSL-like performance for long reach applications. For most efficient use of bit rate and bandwidth flexible framing and on-line reconfiguration methods like Seamless Rate Adaptation (SRA) and Dynamic Rate Repartitioning (DRR) were included as well.

Maximum Speed and Highest Flexibility with the VDSL2/ADSL2+ solution VINAX

The Infineon VDSL2 chip set is available as complete end-to-end solution designed for full VDSL2 bandwidth of 30 MHz. The multi-channel Central Office (CO) chipset is based on a 2-chip architecture enabling line card density of 48 full-rate VDSL2 ports in CO and Remote Terminal (RT) applications. MII, R-MII, S-MII, SS-SMII, POSPHY-L2, and Utopia-L2 interface on the backplane side allow full flexibility and in combination with the built-in AAL5 interworking functionality enable system vendors and telecom providers to deploy VDSL2/ADSL2+ line cards in existing Ethernet and ATM networks. To increase service speed and range the solution integrates a 2-port bonding mechanism and therefore enables service providers to reach 100 percent of their customer base. ADSL-like long reach performance is ensured using Echo Canceller algorithms, Time Domain Equalization and a maximum of 20 dBm line power. All service profiles and regional specific requirements can be met with a single hardware platform by appropriate software configuration.

On the Customer Premises Equipment (CPE) side, Infineon offers a full standard compliant VDSL2 single-chip solution which addresses both simple bridge modems as well as access gateway applications. The VINAX-CPE can be integrated with the company’s new WildPass Wireless Network processor for a complete, ready to deploy, VDSL2 / ADSL2+ gateway reference design.

VINAX-CO is offered in a BGA/TSSOP package. VINAX-CPE comes in a LBGA package. Samples are available now, volume production is planned for the third quarter of Calendar Year 2005.

VINAX is exhibited at the Broadband World Forum in Yokohama, Japan, May 31-June 2, 2005 and at SuperComm 2005 in Chigago, USA, June 6-9, 2005.
