Infineon Technologies Introduces 4-Band VDSL Chipset Family With Support for Fully Standards Compliant ATM Functionality and Industry's First Packet Over VDSL
Munich, Germany February 28, 2002 Infineon Technologies (FSE/NYSE: IFX), a leading provider of integrated circuits for advanced communications systems, today introduced a 4-Band VDSL chipset family featuring two distinct functionalities. The 4bVDSL chipset is a fully standards compliant ATM over VDSL solution, and the PoVDSL chipset is the industrys first Packet over VDSL solution.
Infineon, a recognized leader and innovator in VDSL (Very high bit rate Digital Subscriber Line) technology, will introduce these industry-first chipsets at the FS-VDSL meeting, March 4-6 in Denver, Colorado. With the availability of solutions supporting either ATM or Packet over VDSL, telecommunications equipment manufacturers can produce broadband over copper DSLAMs, switches, and CPE systems offering the highest possible broadband transmission rates.
Telecommunications companies have been eagerly seeking a true, broadband over copper solution to meet market demand for a triple play of integrated fast Internet access, video with high quality streaming media, and voice services delivered over the same copper wire, said Christian Wolff, vice president in Infineon's Communications Group and General Manager of the Access Business Unit. The new 4-Band VDSL family signifies a technological breakthrough, being the first commercially available standards compliant VDSL solution as well as the first to support both ATM and Packet over VDSL functionalities. Incorporating Infineons proven 10BaseS, Ethernet over VDSL technology with standards based 4-band VDSL in a Packet over VDSL solution represents a major step in the adoption of Ethernet in the local copper loop.
Development of standards based 4-band VDSL will ensure an open environment for multi-vendor solutions that is essentially free from the limitations of proprietary designs. The newly adopted VDSL standard allows for up to three video channels and fast Internet access per each line, while leaving legacy voice services unaffected.
The 4-Band VDSL chipset family incorporates vast experience gained by Infineon in worldwide deployment and extensive Telco field trials of the companys 2-band VDSL chipsets. The chipsets are fully compliant with ETSI, ANSI and the recently expanded ITU VDSL standards requirements. The Packet over VDSL chipset goes beyond the ITU standards definition and includes full Ethernet MII layers above the packet transport interface.
With all the necessary functionalities integrated within the chipset, Infineons 4-Band VDSL solution significantly reduces the number of required external components. This high-level integration helps to reduce total cost by lowering the overall bill of material (BOM), reducing system footprint and lowering design complexity at both ends of the network.
Both members of Infineons 4-Band VDSL chipset family build on technologies proven in Infineons market leading 2-band VDSL chipsets and are backward compatible with these products. As with the 2-band chipset, the 4bVDSL and PoVDSL chipsets use Frequency Division Duplexing (FDD) and are based on the widely deployed Quadrature Amplitude Modulation (QAM). The chipsets support both the asymmetrically optimized FSAN Plan 998 as well as symmetrically optimized FSAN Plan 997 and offer 2, 3 or 4-band standard as well as non-standard frequency allocation schemes, providing flexibility in meeting carrier cost and application requirements.
The highly integrated analog and digital architecture features draw on Infineons long history as a supplier of DSL, digital signal processing, modem and analog circuitry, all designed and produced using the companys in-house IC engineering and production expertise.
The chipsets feature all-in-one circuitry including embedded interleaver memory, microprocessor, anti-aliasing filters, gain amplifier, DCXO, ADC and DAC. Both chipsets fully support fast and slow channels, sleep and wake up modes, power back off, blind acquisition and channel equalization. The 4bVDSL and PoVDSL have an integrated controller and flexible software, allowing for operation of the modem as a stand-alone VDSL PHY.
The 4bVDSL ATM based chipset features a dual-latency UTOPIA interface as well as a built-in PCM interface - and is able to transport up to four E1/T1/J1 lines using the same twisted pair. The PCM transport is in parallel to ATM traffic. The 4bVDSL can also operate in RFC-1483 mode, allowing Ethernet traffic encapsulation over the ATM.
The PoVDSL features an MII interface (IEEE 802.3) supporting PTM-TC (HDLC) as per ITU-T G.993.1 standard definition. A PCM transport is in parallel to PTM traffic. The PoVDSL chipset extends Infineons Ethernet service delivery with functionality as a standards-compliant 2, 3, or 4-Band PHY or MAC depending on the application, with backward compatibility support for the existing base of 100s of thousands of 10BaseS VDSL ports.
Infineons 4bVDSL and PoVDSL chipsets are optimized for DSLAM, switch, and CPE applications.
Engineering Samples of Infineons all-inclusive 4-Band VDSL chipset family will be available at the start of Q2/2002. Infineons current 2-band ATM VDSL chipset, used by leading communication system vendors worldwide, continues commercial availability.
