FEATURES

• Monolithic, SONET/SDH Payload

Extractor/Aligner for use in STS-1

(STM-0/AU3), STS-3 (STM-1/AU3) or

STS-3c (STM-1/AU4) interface

applications, operating at serial interface

speeds up to 155.52 Mbit/s.

• Provides integrated clock recovery and

clock synthesis to allow a direct interface

to optical modules.

• Provides termination for SONET Section

and Line, SDH Regenerator Section and

Multiplexer Section transport overhead,

and Path overhead of one or three

STS-1 (STM-0/AU3) paths or a single

STS-3c (STM-1/AU4) path.

• Maps one or three STS-1 (STM-0/AU3)

payloads or a single STS-3c (STM-1/

AU4) payload to system timing

reference, accommodating

plesiochronous timing offsets between

the references through pointer

processing.

• Maps three DS3 bit streams into a

STS-3 (STM-1/AU3) frame.

• Maps three serial data streams (e.g.,

Frame Relay, PPP, or Ethernet

Payload) into a single serial data

stream into a STS-1 (STM-0/AU3) or

STS-3c (STM-1/AU4) payload.

• Supports line loopback from the line

side receive stream to the transmit

stream and diagnostic loopback from a

Telecom ADD bus interface to a

Telecom DROP bus interface.

• Provides a standard 5-signal P1149.1

JTAG test port for boundary scan

board test purposes.

• Provides a generic 8-bit

microprocessor bus interface for

configuration, control, and status

monitoring.

• Low power, +5 V, CMOS technology.

Device has PECL- and TTLcompatible inputs and TTL outputs.

• Available in a 256-pin, Super Ball Grid

Array (SBGA) package.

• Supports industrial temperature range

(-40°C to 85°C) operation.
