DESCRIPTION
The DS21354/554 Single–Chip Transceiver (SCT) contains all of the necessary functions for connection to E1
lines. The device is an upward compatible version of the DS2153 and DS2154 SCTs. The onboard clock/data
recovery circuitry coverts the AMI/HDB3 E1 waveforms to an NRZ serial stream. The DS21354/554
automatically adjusts to E1 22AWG (0.6 mm) twisted–pair cables from 0 to over 2km in length. The device can
generate the necessary G.703 waveshapes for both 75 ohm coax and 120 ohm twisted 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 onboard HDLC controller can be used
for Sa bit links or DS0s. The device contains a set of internal registers which the user can access and control
the operation of the unit. Quick access via the parallel control port allows a single controller to handle many E1
lines. The device fully meets all of the latest E1 specifications including ITU-T G.703,G.704, G.706, G.823,
G.732, and I.431, ETS 300 011, 300 233, and 300 166, as well as CTR12 and CTR4.
