Description

The CD22301 monolithic PCM repeater circuit is designed

for T1 carrier systems operating with a bipolar pulse train of

1.544Mbits/s. It can also be used in the T148 carrier system

operating with a ternary pulse train of 2.37Mbits/s. The cir-

cuit operates from a 5.1V ±5% externally regulated supply.

The CD22301 provides active circuitry to perform all func-

tions of signal equalization and amplification, automatic line

buildout (ALBO), threshold detection, clock extraction, pulse

timing and buffered output formation.
