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 of 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 a DS3 bit stream into a STS-1 (STM-0/AU3) frame or three DS3 bit

streams into a STS-3 (STM-1/AU3) frame.

? Provides clear-channel mapping of three 49.536 Mbit/s or 48.384 Mbit/s

arbitrary data streams into an STS-3 (STM-1/AU3) frame or a single arbitrary

data stream into an STS-1 (STM-0/AU3) frame. Provides clear-channel

mapping of a single 149.76 Mbit/s arbitrary data stream into an STS-3c

(STM-1/AU4) frame.

? Provides versatile datamode interface and optional x^43+1 payload

scrambling/descrambling to support Packet Over SONET applications.

? 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 Volt CMOS. Device has PECL and TTL compatible inputs and

TTL outputs.

? 256 pin Super BGA package. Supports Industrial Temperature Range (-40°C

to 85°C) operation.
