Procurement Notes

Verify the specific suffix 'KILF' against official documentation to confirm lead-free status and tray packaging details. Ensure the order matches the exact pinout and configuration requirements for the target PCB layout. Cross-reference the datasheet revision date to confirm current manufacturing status and availability constraints.

Selection Notes

Select this component when designing systems requiring PCIe Gen 1–6 synchronization with low jitter specifications. The LP-HCSL output interface is suitable for direct connection to standard transmission lines without external termination resistors in many configurations. Verify that the 25 MHz input frequency aligns with the system's oscillator source and that the 3.3V supply voltage matches the board's power distribution network.

Part Context

This part belongs to the 9FGL04xx series of clock generators designed for high-speed serial link applications. It serves as a critical timing element in complex digital systems where precise clock distribution is required for data integrity across multiple lanes.

Replacement Considerations

Direct substitutes within the same family include the 9FGL04P1A000KILF. Verify compatibility regarding output skew and specific configuration bit settings before swapping components in existing designs.
