DS21Q50 Overview
The DS21Q50 E1 quad transceiver contains all the necessary functions for connecting to four E1 lines. The on-board clock/data recovery circuitry coverts the AMI/HDB3 E1 waveforms to an NRZ serial stream. The DS21Q50 automatically adjusts to E1 22AWG (0.6mm) twisted-pair cables from 0km to over 2km in length.
