XRT83L314
14-CHANNEL T1/E1/J1 LONG-HAUL/SHORT-HAUL LINE INTERFACE UNIT
MAY 2004
REV. 1.0.0
GENERAL DESCRIPTION
The XRT83L314 is a fully integrated 14-channel long-
haul and 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
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 generation/
detection, Network Loop Code generation/detection,
TAOS, DMO, and diagnostic loopback modes.
