XRT82D20 Overview
The XRT82D20 is a fully integrated, single channel, Line Interface Unit (Transceiver) for 75 Ω or 120 Ω E1 (2.048 Mbps) applications. The LIU consists of a receiver with adaptive data slicer for accurate data and clock recovery and a transmitter which accepts either single or dual-rail digital inputs for signal transmission to the line using a low- impedance differential line driver. The LIU also includes a...
