78P2241
E3/DS3/STS-1
Transceiver
October 2000
DESCRIPTION
The 78P2241 is a line interface transceiver IC for
E3, DS3, STS-1, NA 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,
multiplexers, SONET Add/Drop multiplexers, PDH
equipment, DS3 to Fiber optic and microwave
modems and ATM WAN access for routers and
switches.
T3/E3
digital
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.
The 28-pin PLCC 78P2241 is pin and functionally
compatible to the 78P7200. It adds a B3ZS/HDB3
ENDEC, loop-back and clock polarity selection as
well as ability to receive a DSX3 monitor signal.
The 78P2241 is manufactured in an advanced
BICMOS process and operates at both 5V and
3.3 V power supply voltages. It consumes less than
95 mA of supply current.
FEATURES
Single chip transmit and receive interface for
E3, DS3 and STS-1 applications.
Interface to 75 ohm coaxial cable over 1100
feet at speeds up to 51.84 Mbps.
Compliant with ANSI T1.102-1993, Telcordia
GR-499-CORE
and
G.703 and G.823 for jitter tolerance.
Compliant with ATM FORUM af-phy-0034 (E3
public UNI) and af-phy-0054 (DS3 public UNI).
Easily Interfaced to ATM framer ICs such as
PMC 7345 , 7346 QJET and 7321.
Unique clock recovery requires no reference
clock or crystal oscillator.
Receive DS3-high and DSX3 monitor signals
Includes diagnostic loop-back for AMI and
digital signals.
Includes a selectable B3ZS/HDB3 ENDEC.
Pin compatible to 78P7200 (28-lead PLCC).
28-lead PLCC and 48-lead TQFP packages
3.3 or 5 V operation, ICC<95mA
Input circuit works either Transformer or
Capacitor coupled
