Infineon Technologies is extending its DSL silicon portfolio with VINAX, a VDSL2/ADSL2+ end-to-end solution positioned for Triple Play services such as multi-channel HDTV, on-line/on-demand gaming and video applications, VoIP and high-speed Internet access. The new Infineon VINAX chipset drives symmetric 100 Mbps over copper wires at distances greater than 350 meters (1150 ft), doubling the loop reach performance of existing VDSL solutions.
Infineon said VINAX is fully compliant to the new VDSL2/ G.993.2 (Very-High-Bit-Rate Digital Subscriber Line 2) standard, which 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 Mbps to symmetric 100 Mbps. 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 canceling 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.
The new 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.
"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.
