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 tristated 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 crystalless jitter attenuator per channel that can be selected either in the transmit or receive path.
The jitter attenuator performance m...
