Cypress (Cypress Semiconductor ) : CY 7B952

SONET/SDH Serial Transceiver

The SONET/SDH Serial Transceiver (SST) is used in Wide Area Network (WAN) 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

• Fully compliant with Bellcore and CCITT (ITU) specifications on:
• Jitter Generation (<0.01 UI)
• Jitter Transfer (<130 kHz)
• Jitter Tolerance
• SONET/SDH and ATM Compliant
• Compatible with PMC-Sierra PM5343
• 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
• 24-pin SOIC
• Compatible with fiber-optic modules, coaxial cable, and twisted pair media
• Power-down options to minimize power or crosstalk
• Low operating current: <65 mA

The IC is manufactured in 0.8 m BiCMOS Technology.

The part is packaged in 24 pin SOIC.
