www.DataSheet4U.com PRELIMINARY XRT75R12 REV. P1.0.2 TWELVE CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT WITH JITTER ATTENUATOR OCTOBER 2003 GENERAL DESCRIPTION The XRT75R12 is a twelve channel fully integrated Line Interface Unit (LIU) featuring EXAR’s R3 Technology (Reconfigurable, Relayless Redundancy) for E3/DS3/STS-1 applications. The LIU incorporates 12 independent Receivers, Transmitters and Jitter Attenuators in a single 420 Lead TBGA package. Each channel of the XRT75R12 can be independently configured to operate in 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.
