Infineon Extends Broadband Chipset Portfolio with Solution for New ADSL2 Standard
The ADSL2 standard, designated as G.992.3/G.992.4 by the International Telecommunications Union (ITU) increases loop reach to serve a higher customer base with ADSL service as well as extensive line diagnostic capabilities and sophisticated power saving modes. Other important features defined by the standard and now supported by the Infineon chipset are fast start up, All Digital Loop (ADL) and channelized voice.
To support the new standard, Infineon upgrades its proven Geminax (Global Enhanced Multiport Integrated ADSL Transceiver) chipset with an ADSL2 compliant data pump. The new chip is plug-in compatible with the existing Geminax chipset. Equipment providers can easily upgrade existing line card designs by simply replacing the data pump chip, providing significant time to market advantage.
The Geminax chipset makes it possible for Infineon customers to provide carriers with cost-effective, high density and low power access network systems supporting transmission of data-only or combined voice and data services. Used in central office digital subscriber line access module (DSLAM) and digital loop carrier (DLC) systems, each Geminax chipset supports eight standards compliant ADSL ports and is fully programmable to meet both ADSL and legacy analog telephony specifications. This combination of standards compatibility and programmability simplifies manufacturing and deployment logistics and reduces total system cost.
Infineon produces both data-only and Integrated Voice/Data (IVD) versions of the Geminax chipset. The Integrated/Voice Data (IVD) version of the chipset is the only available ADSL transceiver chipset with a fully integrated Plain Old Telephone System (POTS) splitter and support for baseband voice processing. This level of integration can significantly reduce Bill of Material (BOM) costs 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 for lifeline voice service.
Samples of the Geminax chipset with support for ADSL2 are now available. More information is available at www.infineon.com/adsl.
