DESCRIPTION
The PM5313 SONET/SDH PAYLOAD EXTRACTOR/ALIGNER (SPECTRA-622) terminates the transport and path overhead of STS-12 (STM-4/AU3 or STM- 4/AU4) and STS-12c (STM-4-4c) streams at 622.08 Mbit/s. The SPECTRA-622 implements significant functions for a SONET/SDH compliant line interface, as well as DS3 mapping.
FEATURES
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.
• Provides Time Slot Interchange (TSI) function at the Telecom ADD and DROP buses for grooming twelve STS-1 (STM-0/AU3) paths or four STS-3/3c (STM-1/AU3/AU4) paths.
• 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.
• Supports OC-48(STM-16) applications by providing parallel receive and transmit line side ports used to connect to front-end OC-48 devices.
• Provides a standard 5 signal IEEE 1149.1 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 3.3V CMOS with TTL compatible digital inputs and CMOS/TTL digital outputs. PECL inputs and outputs are 3.3V and 5V compatible.
• Industrial temperature range (-40°C to +85°C).
• 520 pin Super BGA package.APPLICATIONS
