    LSI (LSI Logic Corperation ) : SpeedREACH AR8101

    5V Analog Front End w/o VCXO

    LSI Logic - SpeedREACH AR8101 The SpeedREACH AR8101 is a Analog Front End (AFE) designed to perform all of the analog
    functions of the receive (RX) and transmit (TX) paths, both full-rate and G.lite, for customer premise modems. By integrating the line driver, AR8101 represents a significant cost reduction for ADSL modem manufacturers, while maintaining the excellent linearity performance of the DPS8001.
    The chip requires no external circuitry beyond a pair of precision resistors and bypass/coupling capacitors.
    Features
    • ADSL CPE AFE with full RX and TX analog signal path including integrated upstream TX line driver
    • Fully monolithic: only 2 precision resistors, 2 non-critical resistors, and decoupling capacitors required
    • Compatible with both ITU G.992.1 (G.dmt) and G.992.2 (G.lite) standards
    • Integrated line driver capable of driving +13 dBM onto the line using a 4.25:1 transformer
    • Power: 1W (driving +13 dBm DMT signal onto the line)
    • Line driver total harmonic distortion for 138 kHz sinewave at 7.4 V peak-to-peak differential with either (a) 11 W resistance load or (b) 5.5 W resistance and 4.25:1 transformer: -85 dB
    • 14-bit linear 4.4 MS/s ADCs and 14-bit linear 4.4 MS/s DACs
    • Entire RX channel linearity: 80 dB MTPR
    • Entire TX channel linearity: 80 dB MTPR
    • RX path noise floor: -160 dBm/Hz
    • 12-bit DAC to support external VCXO
    • 4th-order low-pass filters for RX/TX paths, with ±5% cutoff frequency accuracy
    • TX channel: support for 138 kHz and 276 kHz (for ADSL over ISDN)
    • RX channel: support for both 552 kHz (G.lite) and 1.104 MHz (G.dmt)

    Technology: ADSL
    Package: unknown 0 Pin
    Linux support: No
