    LSI (LSI Logic Corperation ) : SpeedREACH AR8201

    5V Analog Front End

    LSI Logic - SpeedREACH AR8201 The SpeedREACH AR8201 is a Analog Front End (AFE) designed to
    perform all of the analog functions of the receive (RX) and transmit (TX) paths for ADSL customer premise modems — full-rate and G.lite. The AR8201 is also the industry’s first AFE to offer the integrated combination of a +5 V line driver and digitally controlled crystal oscillator (DCXO), eliminating the need for a +12 V supply required when using an external line driver.
    Features
    • ADSL CPE AFE with full RX and TX analog signal path
    • Compatible with both ITU G.992.1 and (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
    • Low-power wakeup detector for G.hs (G.994.1) and ANSI T1E1.413 Issue 7 wakeup protocol
    • Programmable interface for RX/TX digital data
    • Integrated DCXO
    • 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
    • 4th-order low-pass filters for RX/TX paths with a ±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)
    • Entire RX channel linearity: 80 dB MTPR and TX channel linearity: 80 dB MTPR
    • RX input-referred noise at peak gain: –160 dBm/Hz at 300 kHz

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