3.3V 32-1250Mbps AnyRate Micrel, Inc. SY87701L SY87701L CLOCK AND DATA RECOVERY Use lower-power SY87701AL for new designs DESCRIPTION FEATURES Industrial temperature range (40C to +85C) The SY87701L is a complete Clock Recovery and Data Retiming integrated circuit for data rates from 32Mbps 3.3V power supply up to 1.25Gbps NRZ. The device is ideally suited for Clock and data recovery from 32Mbps up to SONET/SDH/ATM and Fibre Channel applications and 1.25Gbps NRZ data stream, clock generation from other high-speed data transmission systems. 32Mbps to 1.25Gbps Clock recovery and data retiming is performed by Complies with Bellcore, ITU/CCITT and ANSI synchronizing the on-chip VCO directly to the incoming specifications for applications such as OC-1, OC-3, data stream. The VCO center frequency is controlled by OC-12, ATM, FDDI, Fibre Channel and Gigabit the reference clock frequency and the selected divide Ethernet as well as proprietary applications ratio. On-chip clock generation is performed through the Two on-chip PLLs: one for clock generation and use of a frequency multiplier PLL with a byte rate source another for clock recovery as reference. The SY87701L also includes a link fault detection Selectable reference frequencies circuit. Differential PECL high-speed serial I/O All support documentation can be found on Micrels web Line receiver input: no external buffering needed site at www.micrel.com. Link fault indication 100k ECL compatible I/O APPLICATIONS Available in 32-pin EPAD-TQFP and 28-pin SOIC packages (28-pin SOIC is available, but NOT SONET/SDH/ATM OC-1, OC-3, OC-12, OC-24 recommended for new designs.)
