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.
The XRT75VL00 incorporates an advanced crystal-less jitter attenuator that can be selected either in the transmit or receive path. The jitter attenuator performance meets the ETSI TBR-24 and Bellcore GR-499 specifications.
The XRT75VL00 provides both Serial Microprocessor Interface as well as Hardware mode for programming and control.
The XRT75VL00 supports local, remote and digital loop-backs. The XRT75VL00 also contains an on-board Pseudo Random Binary Sequence (PRBS) generator and detector with the ability to insert and detect single bit error.
