SONET/SDH PAYLOAD EXTRACTOR/ALIGNER FOR 622 MBIT/S

PROPRIETARY AND CONFIDENTIAL

FEATURES

1.1

General

• Monolithic SONET/SDH PAYLOAD EXTRACTOR/ALIGNER for use in

STS-12 (STM-4/AU3 or STM-4/AU4) or STS-12c (STM-4-4c) interface

applications, operating at serial interface speeds of up to 622.08 Mbit/s.

• Provides integrated clock and data recovery and clock synthesis for direct

connection to optical modules.

• Supports a duplex byte-serial 77.76 Mbyte/s STS-12 (STM-4/AU3 or

STM-4/AU4) or STS-12c (STM-4-4c) line side interface for use in applications

where by-passing clock recovery, clock synthesis, and serializer-deserializer

functionality is desired.

• Supports clock recovery bypass for use in applications where external clock

recovery is desired.

• Complies with Bellcore GR-253-CORE jitter tolerance (1995 issue), jitter

transfer and intrinsic jitter criteria.

• Provides control circuitry to comply with Bellcore GR-253-CORE WAN

clocking requirements related to wander transfer, holdover and long term

stability when using an external VCXO.

• Provides termination for SONET Section and Line, SDH Regenerator Section

and Multiplexer Section transport overhead, and path overhead of twelve

STS-1 (STM-0/AU3) paths, four STS-3/3c (STM-1/AU3/AU4) paths or a single

STS-12c (STM-4-4c) path.

• De-multiplexes an STM-4 receive stream to four STM-1 Telecom DROP bus

streams.

• Multiplexes four STM-1 Telecom ADD bus streams to an STM-4 transmit

stream.

• Maps twelve STS-1 (STM-0/AU3) payloads, four STS-3/3c (STM-1/AU3/AU4)

payloads or a single STS-12c (STM-4-4c) payload to system timing reference,

accommodating plesiochronous timing offsets between the references

through pointer processing.

• Maps twelve DS3 bit streams into an STS-12 (STM-4/AU3) frame.
