Infineon Technologies Broadens Scope of DSL Chipset Solutions; Adds Data-Only ADSL Transceiver to GEMINAX POTS/ADSL Family

Dec 11, 2001 | Technology Media

Munich/Germany – December 11, 2001 – Infineon Technologies (FSE/NYSE: IFX), a leading provider of integrated circuits for advanced communications systems, today introduced a new member of its GEMINAX (Global Enhanced Multiport Integrated ADSL Transceiver) chipset family. The new Data-Only chipset further broadens Infineon’s portfolio of digital subscriber line (DSL) ICs, supporting the company’s strategy to provide end-to-end silicon solutions for the access, metro and optical networks.

Targeted at Access systems with ATU-C (ADSL Transceiver Unit- Central Office) functionality, the GEMINAX, formerly called IVAX, product family now includes both a Data-Only version and an Integrated Voice/Data (IVD) version. The IVD chipset is the only ADSL transceiver chipset with an integrated Plain Old Telephone System (POTS) splitter and support for baseband voice processing. Each GEMINAX chipset supports eight ADSL ports, is fully compliant with International Telecommunications Union (ITU) standards, including G.992.1 (G.dmt) and G.992.2 (G.lite), and is fully programmable to meet both ADSL and legacy analog network specifications. This enables access system providers to use a common design for a “universal line card” that can be deployed globally, providing significant benefits in both logistics and system cost through standardization of materials and assembly.

“Access system providers want to be able to serve global markets while controlling total cost structure and using development resources in the most efficient way possible,” said Christian Wolff, Vice President of Infineon’s Communications Business Group and General Manager of the Access Business Unit. “By expanding the GEMINAX family we now offer our customers a single point of contact for all their ADSL Physical Layer Transceiver needs. When added to the existing ADSL, G.shdsl (symmetric DSL), and VDSL solutions it reinforces Infineon’s leading position as a broad line supplier of innovative DSL chips for access networks.”

Integration Yields Small Footprint and Low Power

The GEMINAX IVD chipset, including all active and passive components and routing, occupies just 1.7 square inches per integrated Voice/Data port, and has a power consumption of less than 1.1 W/Channel for all components, including a 20dBm line driver. The Data-Only version requires just 1.2 square inches per port, and its power consumption is less than 1 W/Channel.

The high-level integration reduces total power dissipation while increasing port density of the system. Thus, GEMINAX-based solutions are easily deployable in the constrained space of both Digital Subscriber Line Access Multiplexer (DSLAM) and Digital Loop Carrier (DLC) environments. Additionally, Bill of Material (BOM) costs can be significantly lowered when compared to multi-board solutions that require bulky and expensive external POTS splitters, ADSL line cards, and a traditional Plain Old Telephone Service (POTS) voice line card.

On-Chip Line Probing and Testing Capabilities

Both versions of the GEMINAX chipset include extensive firmware support for transmission line probing and testing to pre-qualify loops prior to ADSL service activation. This capability allows line testing directly from the line cards, eliminating the need for separate in/out test relays for each channel and external diagnostic test equipment. An integrated toolbox for advanced ADSL and POTS testing accurately analyzes loop length, crosstalk disturbers and expected data rates in single ended configurations. Tests can be conducted with no ADSL customer premise equipment installed.

The GEMINAX chipset family includes the following products.

Integrated Voice/ADSL over POTS (IVD):

GEMINAX-D: High-performance Data DSP
GEMINAX-V: High-performance Voice DSP
GEMINAX-A: Full-rate AFE for ADSL and Voice
GEMINAX-SL: SLIC and line driver

(Configuration with a dual-channel line driver and separate SLIC ICs also is supported.)

ADSL Data Only:

GEMINAX-D: High-performance Data DSP
GEMINAX-L2: ADSL Dual-Channel line driver
GEMINAX-AO: Analog Front End for ADSL

The GEMINAX chipsets are fully compliant with ITU-T G.992.1 (G.dmt)Annex A,B,C,F,G including double upstream, overlapped and non-overlapped spectrum modes, ITU-T G.992 (G.lite) Annex A,B,C , ITU-T G.994.1 (G.hs), ANSI T1.413 Issue 2, and ETSI ETR 328.

A complete suite of evaluation/test tools is available. This includes a complete evaluation package with test and configuration software, reference designs, data sheets, application notes and chipset firmware.

Pricing and Availability

Both versions of the GEMINAX chipset are currently available. In quantities of 10,000 pieces, the Integrated Voice/Data version is priced at US $18 per channel and the Data Only version is priced as US $14 per channel.
