Siemens Microelectronics Adds High-Speed VDSL Chip Solution to POTSWIRE Product Portfolio SAN JOSE, Calif.--(BUSINESS WIRE)--March 23, 1999-- New Digital Subscriber Line Silicon Solution Results from Combining Savan's VDSL Algorithms and Siemens' Mixed Signal Capability Siemens Microelectronics, Inc., today announced the introduction of a new VDSL (Very high bitrate Digital Subscriber Line) integrated chip set to extend the company's POTSWIRE(TM) xDSL product offering. The new VDSL chip set is targeted for manufacturers offering high-speed symmetrical and asymmetrical connections over twisted-pair copper wire. Target applications are high-speed access platforms and modems, LAN connections via twisted pairs, replacement of multiple T1/E1 lines, and related uses. The new POTSWIRE VDSL chip set is the industry's first compact solution to deliver both high-speed symmetrical and asymetrical xDSL services over a single pair of copper wires. The POTSWIRE VDSL is designed to be compatible with POTS (Plain Old Telephone Service) and ISDN (Integrated Services Digital Network) on the same twisted pair and various high-speed data services such as HDSL (High-Speed Digital Subscriber Line) and ADSL (Asymmetric Digital Subscriber Loop) in the same bundle. Siemens' POTSWIRE xDSL chip technology is designed to help manufacturers meet the growing worldwide demand for high-speed data transfer, Internet access, LAN access, and video and audio conferencing. Cahners In-Stat Group predicts that the burgeoning xDSL market will reach 29 million units and $905 million in revenue by the year 2002. The POTSWIRE VDSL chip set consists of three parts: a digital data pump (PEB 22812) an analog front end (PEB 22811) and a line driver IC (PEB 22810). The chip set is based on QAM line code and is fully compliant with emerging VDSL standards. It supports symmetric and asymmetric data rates from 1.5 Mbps to 13 Mbps. At the maximum bit rate (1,300 Mbps symmetrical) a reach of 1,500 meters was achieved even in severely distorted environments. Much longer distances are covered at lower bit rates. The chip set includes a UTOPIA interface to the backplane for ATM-related (Asynchronous Transfer Mode) data streams and line card applications, and a universal data-and-clock interface for a variety of high-speed modem applications. The VDSLchip set also features a low power consumption of 2.5 Watts, much lower than that of conventional DMT based ADSL chip sets, and therefore allows for high-density designs. The next generation of POTSWIRE VSDL chips will offer additional operating modes, faster speeds and a further reduction in power consumption to 1.5 Watts. "This solution clearly offers signifcant advantages over other xDSL technologies for target applications. It delivers high-speed symmetrical and asymmetrical capabilites while still exceeding the transmission distance required for mass deployment," said Uwe Hering, Solution Center Marketing Manager in San Jose. Bringing Together Savan and Siemens Technology The VDSL chip set is the result of a joint development effort between Siemens Semiconductor Group in Munich and Savan Communications Ltd. The new chip set applies Savan's expertise in VDSL algorithms and Siemens' advanced mixed-signal technology. Savan and Siemens recently introduced the QAM-based (Quadrature Amplitude Modulation) VDSL technology to the European Telecommunications Standards Institute (ETSI) standards committee and received much attention within the Full Services Access Networks (FSAN) group. "The range capabilities, as well as compatibility with existing and proposed digital subscriber services, are key to making VDSL products economically viable for telephone service providers," said Dr. Herman Eul, Vice President and head of Siemens Digital Transceivers IC Division. "We anticipate that Savan's new technology will be readily accepted as an industry standard, and we plan to promote that acceptance by integrating their technology into our high-speed, cost-effective chip sets." As part of the agreement, Siemens will license Savan's QAM technology for worldwide distribution. Savan has already utilized the VDSL chip set to develop and supply VDSL solutions and other high-speed modem products to markets worldwide. "Siemens is a market leader with proven expertise in complex mixed signal design; a capability that combines nicely with our algorithm expertise," said Savan's Chief Executive Officer Noam Alroy. "This partnership helps ensure the timely development of cost-effective VDSL solutions. The telecommunications industry as a whole will benefit from Siemens' commitment to produce and distribute these new chip sets." First products based on the new VDSL chip set are currently undergoing testing throughout the world and have thus far received outstanding results. Pricing will be competitive with ADSL chip sets.
