GENERAL DESCRIPTION

The XR-T56L22 is a very low power monolithic repeater/

receiver IC designed for PCM carrier systems operating

between 1.544Mbps and 2.37Mbps. The IC provides all

the active circuitry required to implement one side of a

PCM repeater. The XR-T56L22 features on-chip

adjustable phase shifting, an extracted clock output and

an on-board shunt regulator. The very low power

consumption of the device makes it ideal for long haul

“tandem” repeater applications.
