XRT83SL216IB集成電路（IC）的電信規(guī)格書PDF中文資料

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.
