    USB ADSL Modem Solution

    MTK-20152 USB ADSL Modem Solution

    The ADSL DynaMiTe(TM) chipset from Alcatel Microelectronics provides all the required functions to implement a complete USB-based, rate adaptive ADSL modem. The two-chip-solution consists of the:

    • Optimized ADSL analog front-end chip (MTC-20154)
    • Single-chip ADSL-USB controller (MTC-20158) which includes:
      • DMT modem
      • ARM7TDMI RISC processor
      • ATM framer
      • high-performance USB engine

    ATM cells are transferred over the USB interface. The chipset employs Discrete Multi-Tone modulation as specified in ANSI T1.413 and also supports ITU standards G.992.1 (G.dmt), including Annex B (ADSL-over-ISDN) and G.992.2 (G.lite).
    Reed- Solomon forward error correction with optional interleaving is provided.


    • Integrated MCU, USB and memory controller:
      • USB 1.1 compliant
    • Power consumption of < 1W enables design of bus-powered USB modems
    • Support for multiple ADSL standards:
      • ANSI T1.413 Issue2
      • ITU G.992.1 (G.dmt) Annex A
      • ITU G.992.1 (G.dmt) Annex B (ADSL-over-ISDN)
      • ITU G.992.2 (G.lite)
      • ITU 9.994.1 (g.hs)
    • Rate Adaptive:
      • Up to 8 Mbps downstream
      • Up to 832 Kbps upstream
    • Two-chip USB ADSL modem ? small footprint packages allow compact USB modem design:
      • TQFP-64 (MTC-20154)
      • TBGA-156 (MTC-20158)
    • Complete modem package:
      • No dependency on external processor
      • Full reference design kit for modem manufacturers, including schematics, layout, BOM, hardware design guide, firmware and software drivers
      • Host software for Win 98 SE* / Win 2000* / Win ME* / Macintosh implementation with installation software, miniport drivers, and control panel software
