www.DataSheet4U.com xr MARCH 2005 XRT75R03 REV. 1.0.7 THREE CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT WITH JITTER ATTENUATOR GENERAL DESCRIPTION The XRT75R03 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 XRT75R03 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.
