9FGV0231AKLFT

Overview

The 9FGV0231AKLFT is a PCI Express (PCIe) clock generator and fanout buffer manufactured by Renesas Electronics. It operates with a single input crystal reference to generate up to three outputs at a maximum frequency of 100 MHz. The device utilizes an internal Phase-Locked Loop (PLL) for frequency synthesis and supports HCSL and LVCMOS output types. It functions within a supply voltage range of 1.7 V to 1.9 V and is rated for commercial operating temperatures between 0°C and 70°C. The component is housed in a 24-VFQFN package with exposed pads, measuring 4x4 mm.

Feature Summary

• Integrated PLL-based PCIe clock generation supporting frequencies up to 100 MHz
• Fanout capability providing up to three outputs from a single crystal input
• Flexible output drive options including HCSL and LVCMOS formats
• Low voltage operation at 1.7 V to 1.9 V with 24-pin VFQFN packaging

Applications

• PCI Express (PCIe) system clock distribution
• Server and workstation motherboard timing circuits
• Industrial control systems requiring precise clock synchronization

Procurement Notes

Verify the specific suffix 'AKLFT' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the design accommodates the 1.7 V to 1.9 V supply requirement and the 24-VFQFN thermal pad soldering specifications for reliable surface mount assembly.

Selection Notes

Select this component when a low-jitter, single-input to multi-output solution is required for PCIe interfaces. Compare the 1:3 ratio against other models like the 9FGV0441AKLFT if five outputs are needed. Confirm that the HCSL/LVCMOS output swing matches the receiving device's input requirements without additional level shifting.

Part Context

This part belongs to the 9FGV0231 family of low-power PCIe synthesizers. It serves as a direct replacement for legacy ICS9FGV0231 devices. The 'AKLFT' suffix indicates the specific temperature grade, package type, and tape-and-reel packaging configuration defined by Renesas for this variant.

Replacement Considerations

The 9FGU0231AKILF is a related variant offering LP-HCSL outputs and a wider -40°C to 85°C temperature range, though it requires a different 1.425 V to 1.575 V supply. Verify electrical compatibility before substituting.
