LSI (LSI Logic Corperation ) : SpeedREACH DPS8000

ADSL Full Rate Analog Front End

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) Documentation used to be available at: http://www.lsilogic.com/products/adsl/central_office.html
