Procurement Notes

Verify the specific ordering suffix CNLGI against official documentation to confirm exact package variant and temperature grade. Confirm availability status as product lifecycle stages may affect procurement options.

Selection Notes

Select this component for designs requiring a dedicated PCIe clock source with a 1:2 fan-out. Ensure the design accommodates the 24-VFQFPN footprint and the specified 3.135V to 3.465V power rail requirements.

Part Context

This part belongs to the VersaClock family of timing devices from Renesas. It serves as a specialized solution for generating precise clock signals required by high-speed serial interfaces like PCI Express, differing from general-purpose oscillators by its programmable nature and interface compliance.

Replacement Considerations

Check for direct pin-compatible substitutes within the same VersaClock series or newer generations that maintain the 24-VFQFPN package and PCIe compliance specifications.
