SY69753ALHG Microchip

SY69753AL 3.3V, 125Mbps, 155Mbps Clock and Data Recovery General Description Features The SY69753AL is a complete Clock Recovery and 3.3V power supply Data Retiming integrated circuit for OC-3/STS-3 SONET/SDH/ATM compatible applications at 155Mbps NRZ. The device is ideally Clock and data recovery for 125Mbps/155Mbps NRZ suited for SONET/SDH/ATM applications and other data stream high-speed data transmission systems. Two on-chip PLLs: one for clock generation and Clock recovery and data retiming is performed by another for clock recovery synchronizing the on-chip VCO directly to the incoming Selectable reference frequencies data stream. The VCO center frequency is controlled by Differential PECL high-speed serial I/O the reference clock frequency and the selected divide ratio. On-chip clock generation is performed through the Line receiver input: no external buffering needed use of a frequency multiplier PLL with a byte rate source Link fault indication as reference. 100k ECL compatible I/O The SY69753AL also includes a link fault detection Industrial temperature range (40C to +85C) circuit. Lower power: fully compatible with Micrels Datasheets and support documentation can be found on SY87701V, but with 30% less power Micrels web site at: www.micrel.com.
