Procurement Notes

Verify the exact suffix '426' against official Renesas documentation to confirm pinout and electrical specifications, as generic base part numbers may vary. Confirm current availability status, as this specific variant may be subject to limited supply or end-of-life restrictions. Ensure compatibility with existing system power rails and thermal requirements before procurement.

Selection Notes

Select this component when designing systems requiring precise timing for high-speed serial links such as 10GbE or PCIe. It is suitable for applications needing crystal-to-HCSL conversion with minimal jitter. Consider the 72-VFQFN package size for board space constraints. Verify that the required output frequencies align with the internal PLL capabilities documented in the datasheet.
