XR-T5640 Overview
The XR-T5640 is a monolithic bipolar IC designed for T1 type line receiver application operating at 1.544 M bit/s. It provides all the active circuitry required to perform automatic line build out (ALBO), threshold detection, binary NRZ data and clock recovery. A clock recovery using crystal filter circuit version of the XR-T5640 is also available as XR-T5740.
