1 / 5 page 1 ® 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.
