A 740mW ADSL line driver for central office with 75dB MTPR

Faramarz Sabouri; Reza Shariatdoust

A bipolar ADSL line driver for central office achieves 75dB MTPR. Employing a single-active-termination topology, it has 710mW total dissipation including 20.4dBm delivered to the line. Class-AB biasing makes the 4mA quiescent current independent of process, temperature, and supply variations.

This chip integrates a 4 channel analog front-end for central office ADSL modems. The receive path has a programmable gain amplifier (PGA) with 30 dB of range followed by a fourth-order 2-bit sigma-delta modulator clocking at 35 MHz. The transmit path uses a 14-bit current steering D/A converter followed by a fourth-order low-pass filter. The device is implemented in 0.35 /spl mu/m CMOS and consumes less than 160 mW per channel. It is packaged in a 100 pin MQFP package.
