PM5334 SPECTRA 2x2488
Single-chip SONET/SDH Transport Framer
Documents
Features
Product Overview
The PM5334 SPECTRA 2x2488 device is a feature rich, high-capacity
single-chip SONET/SDH transport framer solution that
enables high-density optical tributary cards for chassis-based
MSPPs, packet MSPPs and ROADMs. The SPECTRA 2x2488 enables
5 Gbit/s of multi-rate multi-port support with unprecedented
power efficiency and carrier-grade reliability
The SPECTRA 2x2488 consists of SONET/SDH line interfaces and
framers with integrated SERDES, including full section, line and
high-order (HO) path processors, non-blocking memory-based HO
STS/AU cross-connect, and TFI-5 compatible ESSI serial backplane
interfaces. The HO cross-connect enables support for selecting
between working, protection and APS traffic.
Benefits
- Enables high-port count, multi-rate optical line cards, while
offering power and space savings
- Integrates multi-rate SERDES for direct connect to SFP modules,
reducing system cost
|
- Integrates best-in-class serial backplane technology, supporting
long trace lengths and bit-sliced architectures
- Integrates field-proven CHESS™ intellectual property,
dramatically reducing development cycles through reuse of
CHESS software base

Product Highlights
SONET/SDH Network Interface and Framer
(ARROW)
- Two groups of four SONET/SDH interfaces, each group
supporting two modes of operation:
- Quad OC-12/3/STM-4/1 mode (four interfaces operating at
622.08 Mbit/s or 155.52 Mbit/s, selectable per port)
- Single OC-48/STM-16 mode (one interface operating at
2488.32 Mbit/s)
- CML compatible serial interfaces to connect to optical
transceivers
- Framing, high-order pointer processing, alarm processing and
overhead processing on all received network streams
|
- Dedicated pins to extract/insert IEC code and N1 path overhead
byte for Tandem Connection Monitoring
- Per-framer connection ID message, allowing verification of high
order path connectivity across single or multistage fabrics
- BLSR and MS-SPRing protection switching with alarm
processing, K-byte express, automatic payload configuration,
and other features
- Insertion/extraction of transport overhead (TOH) bytes from the
line side interface
|
STS/AU Intelligent Cross-Connect (TSE)
- Memory-based, HO cross-connect capable of switching between
any port to any port at STS-1/AU-3 granularity
- 12.5 Gbit/s of floating delay management
- TSE subsystem provides the TOH byte insertion and extraction
on 24 ports (99 TOH bytes per port)
|
- Support for a set of active and standby configuration memory
pages, permitting new switch settings to be updated in one
page while the TSE operates from the control settings of the
other page
- 2.5 Gbit/s to/from 622 Mbit/s interleaving/de-interleaving
- Multiplexing scheme enables different port asset allocations for
different applications
|
Package
- 35 x 35 mm 1152-ball FCBGA

Interfaces
- 20 ESSI (TFI-5) links, all capable of operation at 2.488 Gbit/s or
622 Mbit/s, in support of the following modes:
- 4 ESSI links are APS ports to a mate card
- 16 ESSI links to both a working and protect STS/AU fabric or
client side mappers
- 2/4/8 x 2.488 Gbit/s ESSI links to both a working and protect
sliced STS/AU fabric operating in either nibble, di-bit, or bit
modes
- One 32-bit or four 8-bit 77.76 MHz TelecomBus interfaces
connecting to parallel TelecomBus framers and mappers
|
- SONET/SDH path overhead interface for Tandem Connection
Monitoring
- SONET/SDH HO (STS/AU) transport overhead interface
- SONET/SDH ring control/alarm port
- Standard P1149.1 JTAG test port for boundary scan
- 16-bit microprocessor interface for status monitoring and
configuration
|
Applications
- High fan-in, multi-rate SONET/SDH front-end for line cards for
MSPPs and packet MSPPs
|
- Medium and high density optical line cards for Router and
Switch platforms
