DS2153Q E1 Single-Chip Transceiver

The DS2153Q T1 Single-Chip Transceiver (SCT) contains all of the necessary functions for connection to E1 lines. The onboard clock/data recovery circuitry coverts the AMI/HDB3 E1 waveforms to a NRZ serial stream. The DS2153 automatically adjusts to E1 22 AWG (0.6 mm) twisted-pair cables from 0 to 1.5 km. The device can generate the necessary G.703 waveshape.
