Description

The XRT75L06D is a six channel fully integrated Line Interface Unit (LIU) for E3/DS3/STS-1 applications. The LIU incorporates 6 independent Receivers, Transmitters and Jitter Attenuators in a single 217 Lead BGA package.

Each channel of the XRT75L06D 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.
The XRT75L06D's differential receiver provides high noise interference margin and is able to receive data over 1000 feet of cable or with up to 12 dB of cable attenuation.

The XRT75L06D 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. Also, the jitter attenuators can be used for clock smoothing in SONET STS-1 to DS-3 de-mapping.

The XRT75L06D provides a Parallel Microprocessor Interface for programming and control.

The XRT75L06D supports analog, remote and digital loop-backs. The device also has a built-in Pseudo Random Binary Sequence (PRBS) generator and detector with the ability to insert and detect single bit error for diagnostic purposes.
