Description

The XRT75L03 is a three-Channel fully integrated Line Interface Unit (LIU) and Jitter Attenuator for E3/DS3/STS-1 applications. It incorporates three independent Receivers, Transmitters and Jitter Attenuators in a single 128-Lead QFP package. Each channel of the XRT75L03 can be independently configured to operate in E3 (34.368 MHz), DS3 (44.736 MHz) or STS-1 (51.84 MHz) rates. Each transmitter can be turned off and tri-stated for redundancy support and power conservation.

The XRT75L03's differential receivers provide high noise interference margin and are able to receive the data over 1000 feet of cable, or with cable attenuation of up to 12 dB.

The XRT75L03 incorporates an advanced crystal-less jitter attenuator per channel 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 XRT75L03 provides both Serial Microprocessor Interface as well as Hardware mode for programming and control. The XRT75L03 supports local,remote and digital loop-backs. The XRT75L03 also contains an on-board Pseudo Random Binary Sequence (PRBS) generator and detector with the ability to insert and detect single bit error.
