Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify availability status directly with Renesas Electronics or authorized distributors, as specific suffixes may indicate limited stock or special order requirements. Confirm RoHS compliance details and moisture sensitivity levels prior to procurement. Ensure the ordering part number matches the exact configuration needed, as suffix variations can affect packaging or functional parameters.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single PLL solution with two differential output pairs is required for high-performance networking or computing applications. Verify that the VFQFPN-20 package fits the PCB layout constraints. Ensure the design supports the 1.71 V to 3.465 V supply range and utilizes the I2C interface for configuration if dynamic changes are necessary.

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 by offering higher integration and flexibility through on-chip One-Time Programmable (OTP) memory or I2C configuration. The 5P49V5943B variant specifically targets applications needing multiple output formats from a single reference source.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Check for direct pin-to-pin replacements within the 5P49V59xx series. Verify if the 5P49V5943A000NDGI serves as a compatible alternative based on output count and frequency specifications. Consult Renesas documentation for any obsolescence notices or recommended upgrades for existing designs.
