XRT83D10IW [EXAR]

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. The XRT83D10 uses the transformer coupling on both the Receiver and Transmitter sides, and supports both 120Ω balanced, 75Ω unbalanced and 100Ω interfaces.
