SONET/SDH Serial Transceiver

The SONET/SDH Serial Transceiver (SST) is used in SONET/SDH and ATM applications to recover clock and data information from a 155.52-MHz or 51.84-MHz NRZ or NRZI serial data stream and to provide differential data buffering for the Transmit side of the system. Features are

• SONET/SDH and ATM Compatible
• Compatible with PMC-Sierra PM5345 SUNI (tm)
• Clock and data recovery from 51.84- or 155.52-MHz datastream
• 155.52-MHz clock multiplication from 19.44-MHz source
• 51.84-MHz clock multiplication from 6.48-MHz source
• ±1% frequency agility
• Line Receiver Inputs: No external buffering required
• Differential output buffering
• 100K ECL compatible I/O
• No output clock drift without data transitions
• Link Status Indication
• Loop-back testing
• Single +5V supply
• Compatible with fiberoptic modules, coaxial cable, and twisted pair media
• No external PLL components
• Power-down options to minimize power or crosstalk
• Low operating current: <65 mA
