XRT94L31

3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC

MARCH 2007

REV.1.0.1

APPLICATIONS

GENERAL DESCRIPTION

• Network switches

The XRT94L31 is a highly integrated SONET/SDH

terminator designed for E3/DS3/STS-1 mapping/de-

mapping functions from either the STS-3 or STM-1

data stream. The XRT94L31 interfaces directly to the

optical transceiver.

• Add/Drop Multiplexer

• W-DCS Digital Cross Connect Systems

FEATURES

The XRT94L31 processes the section, line and path

overhead in the SONET/SDH data stream. The

processing of path overhead bytes within the STS-1s

or TUG-3s includes 64 bytes for storing the J1 bytes.

Path overhead bytes can be accessed through the

microprocessor interface or via serial interface.

• Provides DS3/ E3 mapping/de-mapping for up to 3

tributaries through SONET STS-1 or SDH AU-3

and/or TUG-3/AU-4 containers

• Generates and terminates SONET/SDH section,

line and path layers

• Integrated SERDES with Clock Recovery Circuit

The XRT94L31 uses the internal E3/DS3 De-

Synchronizer circuit with an internal pointer leak

algorithm for clock smoothing as well as to remove

the jitter due to mapping and pointer movements.

These De-Synchronizer circuits do not need any

external clock reference for its operation.

• Provides

SONET

descrambling

frame

scrambling

and

• Integrated Clock Synthesizer that generates 155

MHz and 77.76 MHz clock from an external 12.96/

19.44/77.76 MHz reference clock

The SONET/SDH transmit blocks allow flexible

insertion of TOH and POH bytes through both

Hardware and Software. Individual POH bytes for the

transmitted SONET/SDH signal are mapped either

from the XRT94L31 memory map or from external

interface. A1, A2 framing pattern, C1 byte and H1, H2

pointer byte are generated.

• Integrated 3 E3/DS3/STS-1 De-Synchronizer circuit

that de-jitter gapped clock to meet 0.05UIpp jitter

requirements

• Access to Line or Section DCC

• Level 2 Performance Monitoring for E3 and DS3

• Supports mixing of STS-1E and DS3 or E3 and

The SONET/SDH receive blocks receive SONET

STS-3 signal or SDH STM-1 signal and perform the

necessary transport and path overhead processing.

DS3 tributaries

• E3 and DS3 framers for both Transmit and Receive

directions

The XRT94L31 provides a line side APS (Automatic

Protection Switching) interface by offering redundant

receive serial interface to be switched at the frame

boundary.

• Complete Transport/Section Overhead Processing

and generation per Telcordia and ITU standards

• Single PHY and Multi-PHY operations supported

• Full line APS support for redundancy applications

The XRT94L31 provides 3 mappers for performing

STS-1/VC-3 to STS-1/DS3/E3 mapping function, one

for each STS-1/DS3/E3 framers.

• Loopback support for both SONET/SDH as well as

E3/DS3/STS-1

A PRBS test pattern generation and detection is

implemented to measure the bit-error performance.

• Boundary scan capability with JTAG IEEE 1149·8-

bit microprocessor interface·

general-purpose microprocessor interface is

included for control, configuration and monitoring.

• 3.3 V ± 5% Power Supply; 5 V input signal

tolerance

• -40°C to +85°C Operating Temperature Range

• Available in a 504 Ball TBGA package
