9FGV0441AKILFT

Overview

The Renesas 9FGV0441AKILFT is a PCI Express clock generator and fan-out buffer designed for PCIe applications. It features a single PLL circuit with a 1:5 input-to-output ratio, accepting a crystal input to generate outputs up to 100MHz. The device provides both HCSL and LVCMOS output signaling types. It operates on a supply voltage ranging from 1.7V to 1.9V and supports differential input/output configurations. The component is housed in a 32-VFQFPN package with dimensions of 5x5 mm and includes an exposed pad for mounting.

Feature Summary

• PCIe Clock Generator: Designed specifically for PCI Express timing requirements.
• 1:5 Fan-Out Ratio: Distributes one input clock signal to five output channels.
• Dual Output Signaling: Supports both HCSL and LVCMOS output formats.
• Compact Packaging: Utilizes a space-saving 32-VFQFPN (5x5 mm) surface-mount package.

Applications

• PCI Express system clock distribution
• Fan-out buffering for high-speed digital interfaces
• Low-voltage power management systems requiring precise timing

Procurement Notes

Verify the specific suffix 'AKILFT' against manufacturer documentation to confirm temperature range and packaging details, as variations exist within the 9FGV0441 family. Ensure compatibility with the required 1.7V to 1.9V supply voltage during design integration. Confirm that the 32-VFQFPN footprint matches the PCB layout specifications.

Selection Notes

Select this component when a 1:5 clock distribution ratio is required for PCIe architectures. It is suitable for designs operating within the 1.7V to 1.9V voltage window. Consider the 32-VFQFPN package size if board space is constrained. Verify that the target application supports the specified -40°C to 85°C industrial temperature range.

Part Context

The 9FGV0441 series comprises low-power clock generators tailored for PCIe Gen 1 through Gen 4 standards. This specific model variant integrates a phase-locked loop to synthesize frequencies from a crystal reference. The device simplifies system design by providing multiple buffered outputs from a single source, reducing component count compared to discrete buffer solutions.

Replacement Considerations

Cross-reference with other 9FGV0441 variants such as 9FGV0441AKLFT or 9FGV0441DKILFT. Differences may exist in operating temperature ranges, package availability, or specific electrical characteristics. Verify pinout compatibility before substitution.
