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. FIGURE 1. BLOCK DIAGRAM OF THE XRT83SL216
