XRT83VSH38
8-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
MARCH 2007
REV. 1.0.7
GENERAL DESCRIPTION
The XRT83VSH38 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 T1, E1, or J1 mode with minimum external
components. The LIU features are 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.
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.
