Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify availability status as this specific suffix may indicate restricted supply or end-of-life conditions. Confirm RoHS compliance and moisture sensitivity levels before integration. Ensure the ordering suffix matches the required packaging format, as variations exist between tape-and-reel and tray options. Cross-reference the full datasheet for any recent design-in restrictions or recommended alternative parts.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multi-output flexibility and sub-picosecond jitter are critical. Compare against the SI5341A series if higher maximum output frequencies above 800 MHz are required. Verify that the chosen output voltage levels (1.8 V vs 3.3 V) align with the target load requirements. Consider the QFN-64 thermal characteristics for PCB layout optimization in dense designs.
