    ADSL Full Rate Analog Front End

    LSI Logic - SpeedREACH DPS8002 The SpeedREACH DPS8000 is an Analog Front End (AFE) for G.dmt (full-rate) or G.lite ADSL operation.
    Features
    • Complete DMT-based ADSL CO and CPE AFEs with full RX and TX analog signal paths [excluding POTS reject filter and high-voltage line drivers/receivers]
    • Fully monolithic: Only two precision resistors and decoupling capacitors required
    • Support for echo-cancelled and frequency-division based systems; full analog echo path support
    • Compatible with ITU G.992.1 (G.dmt) and G.992.2 (G.lite) standards
    • Supports up to 8 Mbit/s downstream and 800 kbits/s upstream duplex
    • Support for 276 KHz upstream channel for ISDN compatibility
    • 14-Bit Linear 4.416 MS/s ADCs and dual 14-Bit linear 4.416 MHz DACs
    • Programmable RX/TX attenuation/gain
    • 4th-order low-pass filters for RX/TX paths, with ±5% cutoff frequency accuracy
    • RX path noise floor: –160 dBm/Hz
    • 12-bit DAC to support external VCXO
    • Power dissipation:
      – 675 mW for frequency-division mode
      – 825 mW with full echo on
    • Integrated “wakeup” energy detector for CO (DPS8000 only)
