| PMC-Sierra,Inc. PM5342 SPECTRATM-155 * 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 (-40C to 85C) operation. SONET/SDH Payload Extractor/Aligner 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.
