XRT75R03D
EXAR DATA SHEET FORMAT TEMPLATES
MARCH 2006
REV. 1.0.4
GENERAL DESCRIPTION
The XRT75R03D is a three-channel fully integrated
Line Interface Unit (LIU) featuring EXAR’s R3
Technology (Reconfigurable, Relayless Redundancy)
with Jitter Attenuator for E3/DS3/STS-1 applications.
It
incorporates
3
independent
Receivers,
Transmitters and Jitter Attenuators in a single 128 pin
LQFP package.
Each
channel
of
the
XRT75R03D
can
be
independently configured to operate in the data rate,
E3 (34.368 MHz), DS3 (44.736 MHz) or STS-1 (51.84
MHz). Each transmitter can be turned off and tri-
stated for redundancy support or for conserving
power.
The XRT75R03D’s differential receiver provides high
noise interference margin and is able to receive the
data over 1000 feet of cable or with up to 12 dB of
cable attenuation.
The XRT75R03D incorporates an advanced crystal-
less jitter attenuator per channel that can be selected
either in the transmit or receive path. The jitter
attenuator performance meets the ETSI TBR-24 and
Bellcore GR-499 specifications.
The
XRT75R03D
provides
both
Serial
Microprocessor Interface as well as Hardware mode
for programming and control.
The XRT75R03D supports local, remote and digital
loop-backs. The device also has a built-in Pseudo
Random Binary Sequence (PRBS) generator and
detector with the ability to insert and detect single bit
error for diagnostic purposes.

each channel
Jitter Attenuator can be selected in Receive or
Transmit paths
Meets ETSI TBR 24 Jitter Transfer Requirements
Compliant with jitter transfer template outlined in
ITU G.751, G.752, G.755 and GR-499-CORE,1995
standards
Jitter Attenuator can be disabled
CONTROL AND DIAGNOSTICS:
