9FGU0231AKILFT

Overview

The 9FGU0231AKILFT is a PCI Express (PCIe) clock generator and fanout buffer manufactured by Renesas Electronics. It operates with a single PLL circuit to generate outputs from an LVDS or crystal input. The device provides three LP-HCSL or LVCMOS outputs, supporting frequencies up to 100 MHz. It functions within a supply voltage range of 1.425 V to 1.575 V and is rated for industrial temperatures between -40°C and +85°C. The component is housed in a 24-VFQFN package with exposed pads, measuring 4x4 mm.

Feature Summary

• Integrated PLL for low-jitter PCIe clock generation
• Supports LVDS or crystal inputs with 1:3 input-to-output ratio
• Configurable LP-HCSL or LVCMOS output signaling
• Industrial temperature range (-40°C to +85°C)

Applications

• PCI Express Gen1/Gen2/Gen3 system clock distribution
• Server and workstation motherboard clocking
• High-performance computing hardware

Procurement Notes

Verify the specific suffix 'AKILFT' against official Renesas documentation to confirm pinout compatibility and RoHS status. Confirm the moisture sensitivity level (MSL) and reflow soldering profile requirements prior to assembly. Ensure the 24-VFQFN footprint matches the design layout exactly.

Selection Notes

Select this component when a single-ended or differential input must be distributed to three low-power HCSL loads. Verify that the required output frequency does not exceed 100 MHz. Check if the 1.5V supply rail aligns with the target system architecture compared to 1.8V alternatives.

Part Context

This part belongs to the 9FGU0231 family of ultra-low-power PCIe clock synthesizers. It serves as a dedicated timing solution for high-speed serial interfaces, replacing discrete oscillator and buffer combinations to reduce board space and power consumption in dense electronic designs.

Replacement Considerations

The 9FGV0231AKILFT is a related variant offering different output configurations. Verify electrical compatibility before substitution.
