Fujitsu Demonstrating KeyWave Integrated ADSL Modem IC at Broadband Year 99.SAN DIEGO--(BUSINESS WIRE)--July 12, 1999-- Fujitsu Microelectronics, Inc. (FMI) will demonstrate the industry's most highly integrated ATM-based Asymmetric Digital Subscriber Line (communications, protocol) Asymmetric Digital Subscriber Line - (ADSL, or Asymmetric Digital Subscriber Loop) A form of Digital Subscriber Line in which the bandwidth available for downstream connection is significantly larger then for upstream. (ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line ) modem IC at Broadband Year 99 July 14-16. The MB 86670 KeyWave(TM) has been developed by Fujitsu's Network Products Division, based in Manchester, UK, using DSL technology from Orckit Communications Ltd. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on : ORCT) and analog technology from Fujitsu's Mixed Signal Group in Maidenhead, UK. The fully featured Discrete Multi Tone (DMT See DSL. ) modem IC is capable of echo-cancelled operation over POTS or ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. . The product integrates dedicated power-optimising digital processing hardware with a very low-noise, high-resolution analog front end (AFE). Orckit's proven DSL technology has been refined to its third generation for this IC design, benefiting from field experience in large-scale ADSL deployments in the United States and Europe. The IC design provides power efficiency and flexibility. The integrated AFE offers one of the lowest noise receive paths available for ADSL that, together with its world-class 15-bit A-to-D and D-to-A converters, provides superior performance over varied loop conditions. ATM expertise from Fujitsu completes the collaborative design with a UTOPIA cell interface allowing simple interoperation with Fujitsu's family of ATM devices. Additionally, serial data interfaces provide a seamless connection to Fujitsu's MB87976 Ethernet bridge controller for packet-mode applications. The MB86670 KeyWave uses 32 Kbytes of external interleave To intersperse one after the other. See sector interleave and memory interleaving. interleave - interleaving RAM. A host-processor running software supplied by Fujitsu configures and controls the modem's operation. This software configurability allows KeyWave to offer ANSI (American National Standards Institute, New York, www.ansi.org) A membership organization founded in 1918 that coordinates the development of U.S. voluntary national standards in both the private and public sectors. It is the U.S. member body to ISO and IEC. T1.413 Category 2, G.dmt and G.lite modes of operation for both central office (CO) and remote-terminal (ATU-R See ATU. ) applications. An external line driver, transformer and passive R-C hybrid components complete the analog line interface. The high integration of the modem and the ability for a single host to control multiple modems allow high packing densities to be achieved at the CO. The modem's single 3.3-volt supply simplifies ATU-R designs. The MB86670 KeyWave has been designed in 0.35-micron CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. technology using Fujitsu's triple-well process to provide the necessary analog / digital isolation required for low-noise performance. Engineering Samples Customers are now evaluating engineering samples; production will begin in Q4 1999. The KeyWave is in a 240-pin Quad Flat Pack (QFP) package with 0.5-mm pin pitch. Also being evaluated now is the MB86626 KeyWave AFE, which provides the analog performance of the KeyWave in an 80-pin QFP for use with a separate, DSP-based ADSL IC. This device supports one G.dmt channel or two G.Lite channels at the central office.
