XR-T5740
XR-T5740 is PCM AMI Line Receiver and Clock Recovery Circuit manufactured by Exar.
DESCRIPTION
The XR-T5740 is a monolithic bipolar IC designed for T1 line receiver application operating at 1.544 M bit/so It provides all the active circuitry required to perform automatic line build out (ALBO), threshold detection, binary NRZ data and clock recovery as the XR-T5640 but with a crystal filter instead of a LC tank circuit.
A clock recovery using an LC filter circuit version of the XR-T5740 is also available as the XR-T5640.
