    Dual channel AFE: full rate and G.lite

    LSI Logic - SpeedREACH DPS8002 The SpeedREACH DPS8002 is a collection of 2 Analog Front Ends (AFE) for G.dmt (full-rate) or G.lite ADSL operation in a small 12 mm X 12 mm 80-pin package for central office (CO) equipment.
    • ADSL CO AFE with two full RX and TX analog signal paths (excluding POTS reject filter and high-voltage line drivers/receivers)
    • Fully monolithic: minimal external components required (2 precision resistors, 4 non-critical resistors, and decoupling capacitors)
    • Compatible with ITU G.992.1 (G.dmt) and G.992.2 (G.lite) standards
    • Upstream RX channel: support for both 138 kHz and 276 kHz (for ADSL over ISDN)
    • Downstream TX channel: support for both 552 kHz (G.lite) and 1.104 MHz (G.dmt)
    • 14-bit linear 1.104 MS/s ADCs and 14-bit linear 4.416 MHz DACs
    • 4th-order low-pass filters for RX/TX paths, with 5% cutoff frequency accuracy
    • Programmable gain stages and attenuators in RX and TX paths
    • Receive path noise PSD: <-150 dBm/Hz
    • Integrated wakeup detector (no DSP needed for wakeup) supporting both G.hs (G.994.1) and legacy ANSI T1E1.413 Issue 2 wakeup protocols
    • Power: 800 mW max (both channels operating, full-rate mode)
