XRT75VL00D E3/DS3/STS-1 Line Interface Unit with SONET Desynchronizer

The XRT75VL00D is a single-channel fully integrated Line Interface Unit (LIU) with Jitter Attenuator for E3/DS3/STS-1 applications. It incorporates an independent Receiver, Transmitter and Jitter Attenuator in a single 52-pin TQFP package. The XRT75VL00D can be configured to operate in either E3 (34.368 MHz), DS3 (44.736 MHz) or STS-1 (51.84 MHz) modes. The transmitter can be turned off (tri-stated) for redundancy support and for conserving power.
