DESCRIPTION
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 waveshapes for both 75-ohm and 120-ohm cables.
The onboard jitter attenuator (selectable to either 32 bits or 128 bits) can be placed in either the transmit
or receive data paths. The framer locates the frame and multiframe boundaries and monitors the data
stream for alarms. It is also used for extracting and inserting signaling data, Si, and Sa-bit information.
The device contains a set of 71 8-bit internal registers which the user can access to control the operation
