| SY69754AL 3.3V, 622Mbps Clock and Data Recovery The SY69754AL is a complete Clock Recovery and Data Retiming integrated circuit for OC-12/STS-12 applications at 622Mbps 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 SY69754AL also includes a link fault detection circuit. Datasheets and support documentation can be found on Micrel’s web site at: 3.3V power supply • SONET/SDH/ATM compatible • Clock and data recovery for 622Mbps NRZ data stream • Two on-chip PLLs one for clock generation and another for clock recovery • Selectable reference frequencies • Differential PECL high-speed serial I/O • Line receiver input no external buffering needed • Link fault indication • 100k ECL compatible I/O • Industrial temperature range to +85°C • Available in 32-pin EPAD-TQFP • Ethernet media converter • SONET/SDH/ATM OC-12 • Proprietary architecture at 500Mbps to 650Mbps Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 408 944-0800 • fax + 1 408 474-1000 • August 2007 M9999-082107-E or 408 955-1690 Micrel, Inc.
