Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify current availability status as distribution channels may indicate limited stock or special order requirements. Confirm RoHS compliance details through official datasheets before integration. Ensure the VFQFPN-24 package footprint matches the target PCB layout constraints. Validate that the specific suffix corresponds to the required tape and reel or cut tape packaging format for automated assembly processes.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when five independent clock outputs are required with mixed voltage standards. The 0.7 ps jitter specification suits high-speed serial interfaces like 10G Ethernet or PCIe. Verify that the 350 MHz maximum frequency meets the system's clocking needs. Consider the 1.8V/2.5V/3.3V dual-voltage capability if the design requires separate core and output power domains.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Renesas VersaClock 5 family, designed for low-power programmable clock generation. It succeeds earlier generations by offering enhanced flexibility through fractional output dividers and spread spectrum capabilities. The device integrates four fractional output dividers and supports multiple configuration storage options via OTP memory or I2C commands.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The 5P49V5907 is listed as a previous generation alternative but is marked not recommended for new designs. Check for newer VersaClock 6E series devices such as the 5P49V6967 for expanded output copy features. Ensure any substitute maintains the same 350 MHz frequency limit and jitter specifications.
