The 78P234xJAT is TDK Semiconductor’s next generation of Line Interface Unit
with integrated Jitter Attenuator. It is designed and manufactured in state of the
art CMOS process technology, delivering per port the industry's lowest power
consumption line interface transceiver to the market. These devices provide the
greatest flexibility, and offer lower cost solution to the network system designer.
PRODUCT DESCRIPTION
Block Diagram
The 78P234xJAT is a low-power,
2/3/4-port DS3/E3/STS1 transceiver
IC with integrated Jitter Attenuator
(JAT). It includes clock recovery and
transmitter pulse shaping functions for
applications using 75-ohm coaxial
cable at distances up to 1200 feet long
end-to-end or up to 750ft long from a
DS3 cross connect.
The receiver recovers clock and data
from a B3ZS or HDB3 coded AMI
signal. It can compensate for over
12dB of cable and 6dB of flat loss. The
transmitter generates a signal that
meets the standard pulse shape
requirements. It has a selectable
B3ZS/HDB3 ENDEC with a receive
line code violation detector, a local and
remote loop-back mode, an input
