Abstract :
The design techniques used to implement the analogue portions of a single-chip digital subscriber loop transceiver are described. The device provides a full-duplex communication link at l60Kb/s or 80Kb/s over 4Km or 5Km, respectively, of 0.5¿m twisted-pair cable. The 22-pin 27.7mmsq 3um double poly CMOS IC consumes 50mW from single 5 volt supply.
