VARIRATE™ MULTI-RATE TRANSCEIVER WITH SONET RATE
ADAPTATION AND PM
SUMMARY OF BENEFITS
FEATURES
•
Highly integrated rate adaptation device that maps a single STS-3/
STM-1 or a single STS-12/STM-4 stream into STS-48/STM-16 frames
•
Channel Add/Channel Extract functionality for mapping and
extracting lower SONET rates
•
Fully integrated serial clock and data recovery (CDR) 155-Mbps/622Mbps/2.488-Gbps SONET/SDH transceiver
•
Retiming functionality for GbE(SGMII)/FC(CML)/2xFC(CML)/
ESCON(CML)/FICON(CML) rates
•
Retiming functionality for STS-3/STM-1, STS-12/STM-4 and STS-48/
STM-16 rates (CML)
•
MUX/DEMUX functionality for STS-3/STM-1, STS-12/STM-4, and
STS-48/STM-16 rates (4-bit LVDS)
•
MUX/DEMUX functionality for GbE (TBI)/ESCON (10-bit)/FICON
(10-bit)
•
•
Pass-through functionality for other rates (DVB, HDTV etc.)
•
Redundant receive inputs and transmit outputs to facilitate protection
switching designs
•
•
•
2-wire/4-wire serial interface for register access and PM count retrieval
•
•
•
Polarity reversal for differential signals (low and high speed)
•
•
•
•
Core supply: 1.8V
Performance Monitoring (PM) for SONET with optional Section
overhead insertion
Powers down unused blocks via register access
PRBS generators and detectors for inbound/outbound SONET and
inbound/outbound GbE
Bit order swapping for parallel bus (4-bit and 10-bit)
Exceeds SONET requirements for jitter generation, jitter transfer, and
jitter tolerance
• Compliant with Optical Internetworking Forum (OIF),
Telcordia, ITU-T, and IEEE 802.3 standards
• Reduces design cycle and time to market
• Enables new multirate and multiservice features while
retaining existing architectures
• Integrated performance monitoring ensures higher reliability
without sacrificing cost or real estate
• High level of integration allows for higher port density
solutions
• Bit order swap allows for ease of PCB design
• Uses the most effective silicon economy of scale for CMOSbased devices
• Low power consumption eliminates the need for external
cooling sources
