5V/3.3V 32-175Mbps AnyRate Micrel, Inc. SY87700V CLOCK AND DATA RECOVERY SY87700V Use lower-power SY87700AL for 3.3V systems FEATURES 3.3V and 5V power supply options SONET/SDH/ATM compatible AnyRate Clock and data recovery from 32Mbps up to 175Mbps NRZ data stream, clock generation from DESCRIPTION 32Mbps to 175Mbps Two on-chip PLLs: one for clock generation and The SY87700V is a complete Clock Recovery and Data another for clock recovery Retiming integrated circuit for data rates from 32Mbps Selectable reference frequencies up to 175Mbps NRZ. The device is ideally suited for Differential PECL high-speed serial I/O SONET/SDH/ATM applications and other high-speed data Line receiver input: no external buffering needed transmission systems. Clock recovery and data retiming is performed by Link Fault indication synchronizing the on-chip VCO directly to the incoming 100K ECL compatible I/O data stream. The VCO center frequency is controlled by Complies with Bellcore, ITU/CCITT and ANSI the reference clock frequency and the selected divide specifications such as OC-1, OC-3, FDDI, Fast ratio. On-chip clock generation is performed through the Ethernet, as well as proprietary applications use of a frequency multiplier PLL with a byte rate source Available in 32-pin EPAD-TQFP and 28-pin SOIC as reference. packages (28-pin SOIC is available, but not The SY87700V also includes a link fault detection recommended for new designs, see page 2 for circuit. details) Datasheets and support documentation can be found on Micrels web site at: www.micrel.com.
