9FGV0431AKLFT

Overview

The 9FGV0431AKLFT is a PCIe clock generator and support product manufactured by Renesas Electronics. It functions as a general-purpose clock generator supporting PCIe Gen 1, 2, and 3 standards. The device features five output channels with a maximum output frequency of 100 MHz and accepts an input frequency up to 27 MHz. It operates on a single 1.8 V supply voltage and is housed in a 32-lead MLF package. The component exhibits a maximum duty cycle of 55% and has a typical operating supply current of 30 mA.

Feature Summary

• Supports PCIe Gen 1, 2, and 3 architectures
• Five output channels with 100 MHz maximum frequency
• Operates at 1.8 V supply voltage
• Housed in 32-lead MLF surface-mount package

Applications

• PCI Express (PCIe) system clock generation
• General-purpose clock distribution for high-speed digital interfaces
• Server and storage platform timing solutions

Procurement Notes

Verify the specific suffix 'AKLFT' against the manufacturer's official datasheet to confirm pinout, packaging dimensions, and RoHS compliance status. Ensure the ordering information matches the exact electrical specifications required for the target design, particularly regarding the 1.8 V supply requirement and 32-lead MLF package constraints.

Selection Notes

Select this component when a fixed-frequency PCIe clock source is needed for Gen 1 through Gen 3 applications. The 100 MHz output limit defines its suitability for standard PCIe reference clocks. Verify that the 27 MHz maximum input frequency aligns with the available crystal or oscillator sources in the system design.

Part Context

This part belongs to the 9FGV0431 series of clock generators from Renesas. It is distinct from other variants such as the 9FGV0441, which offers different output ratios and frequencies. The 9FGV0431 is specifically optimized for multi-output clock distribution in PCIe environments requiring five synchronized outputs.

Replacement Considerations

Direct replacements within the same family include the 9FGV0431AKLF, which shares identical electrical characteristics but may differ in packaging format (Tray vs. Tape & Reel). Cross-family substitution requires verification of output count, frequency range, and package compatibility.
