Procurement Notes

Verify the specific suffix 'D' against official Renesas documentation to confirm pinout or electrical variations compared to standard variants like the 9FG108EFLFT. Ensure the 48-SSOP package dimensions match the design layout. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring HCSL outputs for PCIe or SATA interfaces. Ensure the input source matches the supported clock or crystal types. Verify that the 400MHz maximum frequency meets the system's timing requirements. Check that the 3.135V to 3.465V supply voltage aligns with the target power rails.

Part Context

This part belongs to the 9FG108 family of frequency generators from Renesas Electronics. Similar parts in this series include the 9FG108EFLFT and 9FG108EGILFT, which share similar core specifications but may differ in package type or specific configuration options. These devices are commonly used in high-performance computing environments requiring precise clock distribution.

Replacement Considerations

The 9FG108EFLFT is a closely related variant within the same family. Verify if the 'D' suffix indicates a specific revision or packaging difference. Cross-reference pinouts and electrical characteristics with the official datasheet to ensure compatibility.
