XRT83SH38
8-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
SEPTEMBER 2006
REV. 1.0.7
GENERAL DESCRIPTION
The XRT83SH38 is a fully integrated 8-channel short-
haul line interface unit (LIU) that operates from a
single 3.3V power supply. Using internal termination,
the LIU provides one bill of materials to operate in T1,
E1, or J1 mode with minimum external components.
The LIU features are programmed through a standard
microprocessor
interface,
controlled through Hardware mode. 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. Key design features
within the LIU optimize 1:1 or 1+1 redundancy and
non-intrusive monitoring applications to ensure
reliability without using relays.
serial
interface
or
The on-chip clock synthesizer generates T1/E1/J1
clock rates from a selectable external clock frequency
and outputs a clock reference of the line rate chosen.
Additional features include RLOS, a 16-bit LCV
counter for each channel, AIS, QRSS generation/
detection, TAOS, DMO, and diagnostic loopback
modes.
