GENERAL DESCRIPTION

The XRT83D10 is a fully integrated, single channel, Line Interface Unit (Transceiver) for 75 Ω or 120 Ω E1 (2.048 Mbps) and 100Ω DS1 (1.544 Mbps) applications. The LIU consists of a receiver with adaptive data slicer for accurate data and clock recovery and a transmitter which accepts dual-rail digital inputs for signal transmission to the line using a low- impedance differential line driver. The LIU also includes a crystal-less jitter attenuator for clock and data smoothing which, depending on system requirements, can be selected in either the transmit or receive path.
