78P2344JAT
4-port E3/DS3/STS-1 LIU
with Jitter Attenuator
PRELIMINARY DATASHEET
JULY 2003
DESCRIPTION
The 78P2344JAT is a low-power, 4-port
DS3/E3/STS1 Line Interface Unit (LIU) 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 1350 feet. These applications include
DSLAMs, T1,3/E1,3 digital multiplexers, SONET
Add/Drop multiplexers, PDH equipment, DS3 to
Fiber optic and microwave modems and ATM WAN
access for routers and switches.
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
B3ZS/HDB3 ENDEC with a receive line code
violation detector, a loop-back mode, an input
receive MUX that can select a redundant channel, a
clock polarity selection mode, and the ability to
receive a DSX3 monitor signal.
FEATURES
Transmit and receive interfaces for E3, DS3 and
STS-1 applications
Designed for use with 75 ohm coaxial cable up
to 1350 ft long end-to-end or up to 900 ft long
from a DS3 cross-connect
Receives DS3-high and DSX3 monitor signals
Local and Remote loopback
Selectable B3ZS/HDB3 ENDEC with line code
violation detector
Standards-based LOS function
Optional serial-port based mode selection and
channel status monitoring
Receiver AGC corrects for up to 6dB of flat loss
Adaptive digital clock recovery (uses line-rate
reference clock input)
Receive output clock maintains nominal line-rate
frequency at all times
Fully integrated Jitter Attenuation function
provided for all line rates (no external VCXO
required)
Jitter Attenuator configurable for transmit or
receive path
Transmit line fault monitor
Requires no external current-setting resistor or
loop filter components
Single 3.3V supply operation
Available in 100-pin Exposed Pad JEDEC LQFP
