Micrel, Inc. 5V/3.3V 32-175Mbps CLOCK AND DATA RECOVERY SY87700V SY87700V s 3.3V and 5V power supply options s SONET/SDH/ATM compatible s Clock and data recovery from 32Mbps up to 175Mbps NRZ data stream, clock generation from 32Mbps to 175Mbps s Two on-chip PLLs one for clock generation and another for clock recovery s Selectable reference frequencies s Differential PECL high-speed serial I/O s Line receiver input no external buffering needed s Link Fault indication s 100K ECL compatible I/O s Complies with Bellcore, ITU/CCITT and ANSI specifications such as OC-1, OC-3, FDDI, Fast Ethernet, as well as proprietary applications s Available in 32-pin EPAD-TQFP and 28-pin EPAD SOIC packages 28-pin SOIC is available, but not recommended for new designs The SY87700V is a complete Clock Recovery and Data Retiming integrated circuit for data rates from 32Mbps up to 175Mbps NRZ. The device is ideally suited for SONET/SDH/ATM applications and other high-speed data transmission systems. Clock recovery and data retiming is performed by synchronizing the on-chip VCO directly to the incoming data stream. The VCO center frequency is controlled by the reference clock frequency and the selected divide ratio. On-chip clock generation is performed through the use of a frequency multiplier PLL with a byte rate source as reference. The SY87700V also includes a link fault detection circuit.
