9FGU0641AKILF

Overview

The 9FGU0641AKILF is a clock generator integrated circuit manufactured by Renesas Electronics, designed for PCI Express (PCIe) applications. It supports PCIe Gen1, Gen2, and Gen3 standards with an output frequency of up to 150 MHz. The device operates on a single 1.8V supply voltage and features LVDS differential inputs alongside LP-HCSL differential outputs. Packaged in a compact 24-VFQFN exposed pad format measuring 4x4 mm, it functions within an industrial temperature range of -40°C to +85°C. This component integrates a Phase-Locked Loop (PLL) for precise frequency synthesis.

Feature Summary

• Supports PCIe Gen1, Gen2, and Gen3 clock generation requirements
• Integrates PLL for low-jitter frequency synthesis up to 150 MHz
• Converts LVDS differential input signals to LP-HCSL differential outputs
• Operates on a single 1.8V power supply rail

Applications

• PCI Express peripheral cards and add-in boards
• Server and workstation motherboard chipset interfaces
• Storage controller systems requiring PCIe compliance

Procurement Notes

Verify the specific suffix 'AKILF' against official Renesas documentation to confirm package type, lead-free status, and tape-and-reel configuration. Confirm current lifecycle status as distribution data may vary. Ensure compatibility with existing PCB footprints for the 24-VFQFN package before procurement.

Selection Notes

Select this component when a PCIe-compatible clock source with LVDS input and LP-HCSL output is required. Verify that the 150 MHz maximum frequency meets system timing constraints. Ensure the design accommodates the 1.8V supply requirement and the thermal characteristics of the VFQFPN-24 package for the target operating environment.

Part Context

This part belongs to the 9FGU series of PCIe clock generators from Renesas. It serves as a specialized timing solution for high-speed serial interface applications, distinct from general-purpose clock buffers or multi-output fan-out devices found in other product lines.

Replacement Considerations

Consult Renesas official cross-reference tools for verified pin-to-pin compatible alternatives. Generic clock generators may not support the specific PCIe signaling standards or input/output voltage levels required for direct substitution.
