Application Specific Clock/Timing Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the Tape and Reel packaging format as specified in the datasheet. Confirm the Pb-Free status indicated by the 'H' suffix and check for the NiPdAu bar line indicator. Ensure compatibility with commercial temperature ranges and validate pin configurations against the 32-pin EPAD-TQFP layout.

Application Specific Clock/Timing Selection Notes

Select this component for designs requiring clock recovery and data retiming at speeds between 32Mbps and 175Mbps. Consider the 32-pin EPAD-TQFP package for thermal management and signal integrity. Evaluate the need for external loop filter components based on specific jitter tolerance requirements and ensure proper termination of unused outputs to conserve power.
