GENERAL DESCRIPTION
Clock recovery and data retiming is performed by synchronizing the on-chip VCO directly to the incoming data stream. On-chip clock generation is performed through the use of a frequency multiplier PLL with a byte rate source as reference. The SY69753AL also includes a link fault detection circuit. Datasheets and support documentation can be found on Micrel’s web site at:FEATURES
