XRT75L04D Overview
The XRT75L04D is a four-channel fully integrated Line Interface Unit (LIU) with Sonet Desynchronizer for E3/DS3/STS-1 applications. It incorporates four independent Receivers, Transmitters and Jitter Attenuators in a single 176 pin QFP package. Each channel of the XRT75L04D can be configured to operate in E3 (34.368 MHz), DS3 (44.736 MHz) or STS-1 (51.84 MHz) rates that are independent of each other.
