DESCRIPTION
The DS2154 Enhanced Single–Chip Transceiver
(ESCT) contains all of the necessary functions for con-
nection to E1 lines. The device is an upward compatible
version of the DS2153 Single–Chip Transceiver. The
onboard clock/data recovery circuitry coverts the AMI/
HDB3 E1 waveforms to a NRZ serial stream. The
DS2154 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 multi-
frame 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 internal registers which the user can
access to 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 G.703, G.704,
G.706, G.823, G.932, and I.431 as well as ETS 300 011,
300 233, 300 166, TBR 12 and TBR 13.
