P1.0.3 GENERAL DESCRIPTION The XRT83SL216 is a fully integrated 16-channel E1 short-haul LIU which optimizes system cost and performance by offering key design features. The XRT83SL216 operates from a single 3.3V power supply. The LIU features are programmed through a standard serial microprocessor interface. EXAR’s LIU has patented high impedance circuits that allow the transmitter outputs and receiver inputs to be placed in a high impedance mode when experiencing a power failure or when the LIU is powered off. Additional features include TAOS for transmit and receive, RLOS, LCV, on chip Jitter Attenuator, AIS detector, and diagnostic loopback modes. APPLICATIONS • ISDN Primary Rate Interface • CSU/DSU E1 Interface • E1 LAN/WAN Routers • Public Switching Systems and PBX Interfaces • E1 Multiplexer and Channel Banks • Integrated Multi-Service Access Platforms (IMAPs) • Integrated Access Devices (IADs) • Inverse Multiplexing for ATM (IMA) Wireless Base Stations FIGURE 1.
