Application Specific Clock/Timing Procurement Notes

Verify the specific suffix 'EKLF' against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with Intel CPU-M specifications before integration. Check current product status as timing ICs may undergo lifecycle changes. Confirm MSL handling requirements during storage and assembly processes.

Application Specific Clock/Timing Selection Notes

Select this component when designing for Intel CPU-M or standard Intel CPU platforms requiring dedicated PCIe clock synthesis. Compare against general-purpose oscillators if lower integration is acceptable. Evaluate the 72-VFQFPN footprint constraints against PCB layout capabilities. Consider the single-output limitation versus multi-clock generator alternatives.
