Application Specific Clock/Timing Procurement Notes

Verify the specific suffix BGLF against the official Renesas datasheet to confirm package dimensions and pinout compatibility. Confirm that the component meets RoHS3 specifications as indicated in public records. Check for any Product Change Notifications regarding material or assembly site changes prior to integration. Validate that the 56-TFSOP footprint matches the target PCB design constraints.

Application Specific Clock/Timing Selection Notes

Select this component when designing mobile platforms requiring a single-chip solution for Intel P4-M architecture. Ensure the design supports a 14.318MHz crystal input and requires differential LVDS-style outputs for CPU and PCIe lanes. Consider the 3.3V operating voltage and thermal characteristics suitable for the intended application environment.

Application Specific Clock/Timing Part Context

This part belongs to the IDT/Renesas Timing Control Hub family, originally developed by Integrated Device Technology before acquisition. It serves as a specialized clock generator for legacy mobile computing architectures. The product line has been transitioned to SiTime, though documentation remains available through Renesas channels until late 2026.

Application Specific Clock/Timing Replacement Considerations

Public records indicate a transition of the timing product portfolio to SiTime. Verify if SiTime offers direct functional equivalents for Intel P4-M era designs. Consult official substitution guides for cross-reference data.
