XRT83VSH314
14-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
SEPTEMBER 2006
REV. 1.0.1
GENERAL DESCRIPTION
The XRT83VSH314 is a fully integrated 14-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 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.
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).
Additional features include RLOS, a 16-bit LCV
counter
for
each
channel,
AIS,
QRSS/PRBS
generation/detection, TAOS, DMO, and diagnostic
loopback modes.
