9FGU0431AKILF

Overview

The 9FGU0431AKILF is a clock generator IC designed for PCI Express (PCIe) applications, manufactured by Renesas Electronics. It supports PCIe Gen 1, 2, and 3 standards with a maximum output frequency of 156.25 MHz. The device features one circuit with an input-to-output ratio of 1:3. It accepts LVDS or crystal inputs and provides LP-HCSL or LVCMOS outputs. Powered by a single 1.425V to 1.575V supply, it operates within a temperature range of -40°C to +85°C. The component is housed in a 24-VFQFN package with exposed pads.

Feature Summary

• Supports PCIe Gen 1/2/3 clock generation up to 156.25 MHz
• Integrates a PLL for low-jitter clock synthesis
• Flexible output options including LP-HCSL and LVCMOS
• Low voltage operation at 1.5V nominal

Applications

• PCI Express root complex clocking
• PCI Express switch clock distribution
• High-speed serial interface timing solutions

Procurement Notes

Verify the specific suffix 'AKILF' against the official Renesas datasheet to confirm pinout, packaging dimensions, and RoHS compliance status. Ensure the ordering information matches the required tape-and-reel quantity and moisture sensitivity level before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a single-input, three-output PCIe clock generator is required for Gen 1 through Gen 3 systems. Compare input requirements (LVDS vs. Crystal) and output load capabilities against the target design. Verify that the 24-VFQFN package footprint fits the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the 9FGU series of PCIe clock generators from Renesas. It serves as a timing solution for high-speed data transmission interfaces. The series typically includes variants with different output counts and frequencies to support various system architectures.

Replacement Considerations

Check for direct replacements within the 9FGU series or compatible 9FGV series devices. Ensure substitute parts maintain the same I/O ratios, voltage levels, and package types. Verify electrical parameter compatibility before substitution.
