SPECTRA-4x155

Quad Channel 155 Mbit/s SONET/SDH Framer and Aligner

PM5316

FEATURES

• Monolithic four channel SONET/SDH Payload Extractor/Aligner for use in STS-3 (STM-1/AU-3) or STS-3c (STM1/AU-4) interface applications, operating at serial interface speeds of

155.52 Mbit/s.

• Provides integrat ed clock re covery and clock synthesis to allow direct interface to optical modules.

• Each channel provides termination for SONET Section and Line, SDH Regenerator Section and Multiplexer Section transport overhead, and path overhead of three STS-1 (STM-0/AU-

3) paths or a single STS-3c (STM1/AU-4) path.

• Each channel maps three STS-1 (STM-0/AU-3) payloads or a single STS-3c (STM -1/AU-4) payload to system timing reference, accommodating plesiosynchronous timing offsets between the references through pointer processing.

• The entire SONET/SDH transport and path overheads are extracted to and inserted from dedicated pins.

• Frames to the SONET/SDH receive stream and inserts framing bytes and STS identification into the transmit stream and processes or inserts the transport overhead.

• Interprets or generates the STS (AU) pointer bytes (H1, H2, H3), extracts or inserts the synchronous payload envelope(s) and processes or inserts the path overhead.

• Supports Automatic Protection Switching (APS):

• Ring control port communication of

path REI and path RDI alarms;

• Filters the APS channel (K1,K2)

bytes into internal registers; inserts the APS channel into the transmit stream.

• Provides Time Slot Interchange (TSI) function at the ADD and DROP TelecomBus Interfaces for groomi ng twelve STS-1 (STM-0/AU-3) paths.

• Supports line loopback from the line side receive stream to the transmit stream and diagnostic loo pba ck from an ADD TelecomBus interface to a DROP TelecomBus interface.

• Provides a standard five signal P1149.1 JTAG test port for boundary scan board test purposes.

• Provides a generic 8-bit microprocessor bus interface for configuration, contro l, and sta tus monitoring.

• Low power 3.3 V CMOS with TTL compatible digital inputs and CMOS/TTL digital outputs.

• Industrial temperature range (-40°C to +85°C).

• 520 pin Super BGA package.

• Supports clock recovery bypass for

use in applications where external clock recovery is desired.

• Complies with Bellcore GR-253-CORE jitter tolerance, jitter transfer, and intrinsic jitter criteria.
