Description

Description

The XRT83VSH316 is a fully integrated 16-channel short-haul line interface unit (LIU) that operates from a 1.8V Inner Core and 3.3V I/O power supplies. Using internal termination, the XRT83VSH316 LIU provides one bill of materials to operate in T1, E1, or J1 mode independently on a per channel basis with minimum external components. The LIU features are programmed through a standard parallel microprocessor interface or SPI (Serial Mode). EXAR's XRT83VSH316 LIU has patented high impedance circuits that allow the transmitter outputs and receiver inputs to be high impedance when experiencing a power failure or when the LIU is powered off. Key design features within the XRT83VSH316 LIU optimize 1:1 or 1+1 redundancy and non-intrusive monitoring applications to ensure reliability without using relays.The on-chip clock synthesizer generates T1/E1/J1 clock rates from a selectable external clock frequency and has five output clock references that can be used for external timing (8kHz, 1.544Mhz, 2.048Mhz, nxT1/J1, nxE1). Additional features include System Side LOS, AIS, QRSS/PRBS and Line Side RLOS, AIS, QRSS/ PRBS, DMO with 16-bit LCV counters and diagnostic loopback modes for each channel.
