FEBRUARY 2004
GENERAL DESCRIPTION
The XRT75VL00 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 XRT75VL00 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. The XRT75VL00’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.
