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).
