8-CHANNEL E1 SHORT-HAUL LINE INTERFACE UNIT
XRT83VSH28
AUGUST 2006
REV. P1.0.0
GENERAL DESCRIPTION
The XRT83VSH28 is a fully integrated 8-channel
short-haul line interface unit (LIU) that operates from
a 1.8V and a 3.3V power supply. Using internal
termination, the LIU provides one bill of materials to
operate in E1 75
or 120
mode with minimum
external
components.
The
programmed through a standard parallel or serial
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. Key design features within the LIU
optimize 1:1 or 1+1 redundancy and non-intrusive
monitoring applications to ensure reliability without
using relays.
LIU
features
are
The on-chip clock synthesizer generates an E1 clock
reference.
Additional features include RLOS, a 16-bit LCV
counter for each channel, AIS, QRSS generation/
detection, TAOS, DMO, and diagnostic loopback
modes.
