GENERAL DESCRIPTION

The XRT83SL314 is a fully integrated 14-channel

short-haul line interface unit (LIU) that operates from

a single 3.3V power supply.

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

microprocessor interface. EXAR’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.

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).
