9FGV0441AKLF

Overview

The Renesas 9FGV0441AKLF is a clock generator designed for PCI Express (PCIe) applications. It operates on a single 1.7V to 1.9V supply and supports a maximum frequency of 100MHz. The device features one circuit with a 1:5 input-to-output ratio, utilizing a crystal input and providing HCSL and LVCMOS outputs. It is housed in a 32-VFQFPN package with an exposed pad, measuring 5x5 mm. The component is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrated PLL for precise clock generation
• Supports PCIe main-purpose applications
• Dual output signaling types: HCSL and LVCMOS

Applications

• PCI Express system timing
• Computer motherboards
• Peripheral cards requiring low jitter clocks

Procurement Notes

Verify the specific suffix 'LF' against the manufacturer's datasheet to confirm lead-free status and RoHS compliance. Ensure the 32-VFQFPN package dimensions match the target PCB footprint. Confirm that the 0°C to 70°C commercial temperature range meets the environmental requirements of the final assembly.

Selection Notes

Select this component when a 1:5 fan-out buffer is required for PCIe designs. The 1.8V nominal supply voltage aligns with modern low-power logic standards. Verify that the external crystal frequency matches the device's input specifications to achieve the desired 100MHz output.

Part Context

This part belongs to the Renesas clock generator family optimized for high-speed serial interfaces. It serves as a distribution buffer to drive multiple receivers from a single reference source, reducing board space compared to discrete solutions.

Replacement Considerations

Check for direct pin-compatible replacements within the same Renesas series. Verify that alternative parts support the same 1:5 ratio and output voltage levels.
