78P2241B
E3/DS3/STS-1
Transceiver
August 2001
DESCRIPTION
The 78P2241B 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, 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.
The 28-pin PLCC 78P2241B is pin and functionally
compatible to the 78P7200L and the 78P2241 (28
PLCC version). The 78P2241B in the 48-pin TQFP
is pin compatible with the 78P2241 in the same
package. To the 78P7200L functionality, it adds a
B3ZS/HDB3 ENDEC, line code violation detector,
loop-back and clock polarity selection as well as
ability to receive a DSX3 monitor signal. The line
code violation detector has been added to the
78P2241 functionality.
The 78P2241B is manufactured in an advanced
BICMOS process and operates at both 5V and
3.3 V power supply voltages. It consumes less than
110 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
GR-253-CORE,
G.703, G.823 for jitter tolerance, and G.775
for loss of signal.
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)
and 78P2241.
28-lead PLCC and 48-lead TQFP packages
3.3 or 5 V operation, ICC<110mA
Input circuit works either Transformer or
Capacitor coupled
