XRT83VSH316 16-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT AUGUST 2017 REV. 1.0.3 GENERAL 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 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). MaxLinear’s 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 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 ...
