Procurement Notes

Verify the specific suffix 'B' against official Renesas documentation to confirm any deviations from the standard 'C' variant regarding package type or temperature grade. Confirm RoHS compliance status through the manufacturer's current environmental declaration. Check for moisture sensitivity level requirements during handling and storage procedures.

Selection Notes

Select this component when an eight-channel zero-delay buffer with 85-ohm termination is required for 3.3V PCIe designs. Ensure the input clock frequency falls within the operational limits defined in the datasheet. Verify that the 8-pin SOIC package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the 9DBL0851 family of clock buffers. The 'CKILF' designation typically denotes the standard commercial/industrial version, while the 'BKILF' suffix indicates a specific manufacturing lot or minor revision. It serves as a critical timing element in high-speed serial link architectures.

Replacement Considerations

Direct substitutes may include other 8-output zero-delay buffers with compatible voltage levels and impedance. Verify pin compatibility and electrical specifications before swapping. Consult Renesas for officially qualified alternatives if supply chain constraints exist.
