Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '633' against official Renesas documentation to confirm the exact factory configuration and pinout compatibility. Check current lifecycle status as some VersaClock 5 variants are marked as Not Recommended for New Designs (NRND). Confirm RoHS compliance details directly from the manufacturer datasheet before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low jitter performance below 1 ps is required for high-speed serial links. Ensure the design accommodates the 24-VFQFN thermal pad requirements for adequate heat dissipation. Verify that the system power rails align with the 1.8 V, 2.5 V, and 3.3 V operating specifications supported by the VersaClock 5 family.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the VersaClock 5 series, representing Renesas' fifth generation of programmable clock technology. It is designed to replace older generations like the VersaClock 4 in applications demanding stricter jitter budgets. The device integrates fractional output dividers and independent spread spectrum capability for electromagnetic interference reduction.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The 5P49V5907 is listed as a related alternative within the same product family. Engineers should evaluate the 5P49V6967 if additional output copies or VersaClock 6E features are required. Cross-referencing pinouts and OTP programming methods is essential when transitioning between these variants.
