9FGL0841AKILF

Overview

The 9FGL0841AKILF is a PCI Express (PCIe) clock generator IC from the Renesas 9FGL series. It features a single PLL circuit with a 1:9 input-to-output ratio, providing nine differential outputs. The device operates on a 3.3V supply voltage (3.135V to 3.465V) and supports a maximum output frequency of 100MHz. It utilizes crystal or LVCMOS inputs and delivers HCSL or LVCMOS output types. Packaged in a 48-VFQFN (6x6mm) with an exposed pad, it is designed for low-power PCIe applications within an operating temperature range of -40°C to +85°C.

Feature Summary

• Nine differential outputs supporting PCIe Gen1-Gen3 standards
• Single PLL architecture with 1:9 input-to-output ratio
• 3.3V supply operation with HCSL/LVCMOS output compatibility
• Compact 48-VFQFN surface-mount package

Applications

• PCI Express peripheral cards
• Server and workstation motherboard clock distribution
• Industrial control systems requiring PCIe connectivity

Procurement Notes

Verify RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly. Confirm package marking updates via recent Product Change Notifications (PCNs). Check current component availability as some distributors list this part as obsolete or end-of-life.

Selection Notes

Select this component when nine synchronized differential clocks are required for PCIe interfaces. Ensure the design accommodates the 48-pin VFQFN footprint and 3.3V power domain. Verify that the 100MHz maximum frequency meets system timing requirements.

Part Context

This part belongs to the 9FGL family of low-power PCIe clock generators. It serves as a specialized solution for multi-lane PCIe expansion slots and chipset connections, differing from the 9FGU and 9FGV series by its specific 3.3V voltage profile and 9-output configuration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 9FGL series variants only if pinout and electrical specifications match exactly.
