78P2241B

E3/DS3/STS-1

Line Interface Unit

DATA SHEET

JULY 2005

DESCRIPTION

FEATURES

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.

•

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, ITU-T

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.

•

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.

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

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.

•

Line-code violation detector

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.
