KeyWave ADSL Transceiver/Controller

The KeyWave ADSL Transceiver/Controller, from Fujitsu, is the key component for Asymetrical Digital Subscriber Line (ADSL) modems supporting Discrete Multi Tone (DMT) modulation. This highly integrated device supports Category II ADSL functionality as defined by ANSI T1.413, including trellis encoding and echo cancellation, with bit rates programmable up to 1 Mbps upstream and 8 Mbps downstream. The device includes a hardware DMT modulator/demodulator with digital signal processor (DSP) support, framer and user interfaces, high resolution A/D and D/A convertors and active filtering, which significantly reduces the requirement for external components.

Features Supports ANSI T1.413 Issue 2 and ETSI 328 DMT ADSL Programmable for future ADSL derivatives (e.g. G.Lite, UADSL) Configurable as Central Office (ATU-C) or Remote (ATU-R) ADSL Termination Unit Integrated 15-bit resolution A/D and D/A convertors and active filtering Low noise Receive path summing amplifier (2.5 nV/÷Hz typical) Analogue and digital echo cancellation Six configurable serial data interfaces UTOPIA data interface, Level 2 PHY layer or Level 1 ATM layer Supports Rate Adaptation (programmable N x 32 kbps channel allocation) Compatible with POTS and ISDN Low power operation (< 2 Watts typical) General purpose microprocessor interface 3.3V CMOS device
