78P2243
Triple E3/DS3/STS-1
Transceiver
June 2000
DESCRIPTION
The 78P2243 is a triple channel version of the
78P2241. Each of the three ports is a line interface
transceiver for E3, DS3, STS-1, North America T3 and
ATM applications. It includes clock recovery and
transmitter pulse shaping functions for applications
using 75-ohm coaxial cable at distances up to 1100
feet. These applications include DSLAMs, T3/E3 digital
multiplexers, SONET Add/Drop multiplexers, PDH
equipment, DS3 to Fiber optic and microwave modems
and ATM WAN access for routers and switches.
Each receiver recovers clock and data from a B3ZS or
HDB3-coded AMI signal. The receiver can compensate
for over 12dB of cable and 6dB of flat loss. The
transmitter has a B3ZS/HDB3 ENDEC with a receive
line code violation detector, a loop-back mode, a clock
polarity selection mode, and the ability to receive a
DSX3 monitor signal. Signals generated meet the
standard pulse shape requirements.
The 78P2243 is manufactured in an advanced
BiCMOS process and operates at both 3.3V and 5V
power supply voltages.
