XRT83SL216
16-CHANNEL E1 SHORT-HAUL LINE INTERFACE UNIT
DECEMBER 2005
GENERAL DESCRIPTION
APPLICATIONS
REV. P1.0.3
The XRT83SL216 is a fully integrated 16-channel E1
short-haul LIU which optimizes system cost and
performance by offering key design features. The
XRT83SL216 operates from a single 3.3V power
supply. The LIU features are programmed through a
standard serial microprocessor interface. EXAR’s LIU
has patented high impedance circuits that allow the
transmitter outputs and receiver inputs to be placed in
a high impedance mode when experiencing a power
failure or when the LIU is powered off. Additional
features include TAOS for transmit and receive,
RLOS, LCV, on chip Jitter Attenuator, AIS detector,
and diagnostic loopback modes.
• ISDN Primary Rate Interface
