PMC PM5342 Datasheet
PMC-Sierra,Inc.
SONET/SDH Payload Extractor/Aligner
PM5342
SPECTRA™-155
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, operat ing at s erial in terface
speeds up to 155.52Mbit/s.
• Provides integrated clo ck recovery and
clock synthesis to allow a direct int erface
to optical modules.
• Provides termination fo r SONET Section
and Line, SDH Regenerator Se ction an d
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.
BLOCK DIAGRAM
• 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 diagno stic loopbac k from a
Telecom ADD bus interface to a
Telecom DROP bus interface.
• Provides a standard 5-signal P1149.1
JTAG test por t for boundary scan
board test purposes.
• Provides a generic 8-bit
microprocessor bus inter face 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
(-40°C to 85°C) operation.
