9FGV0831CKLF

Overview

The Renesas 9FGV0831CKLF is a clock generator designed for PCI Express applications. It features one circuit with an input-to-output ratio of 1:9, supporting up to 100 MHz maximum frequency. The device accepts crystal inputs and provides HCSL and LVCMOS outputs. It operates on a 1.7 V to 1.9 V supply voltage within a commercial temperature range of 0°C to 70°C. Packaged in a 48-VFQFPN (6x6) surface-mount format, it integrates PLL functionality for precise timing generation.

Feature Summary

• Supports PCI Express applications with 1:9 output ratio
• Provides HCSL and LVCMOS output signaling types
• Operates at frequencies up to 100 MHz
• Integrated PLL for clock generation from crystal input

Applications

• PCI Express system clocking
• Crystal-based clock generation circuits
• Low-voltage digital logic interfacing

Procurement Notes

Verify the specific suffix 'CKLF' against official documentation to confirm the operating temperature range and package details. Ensure compatibility with the required 1.7 V to 1.9 V power supply rails. Confirm that the 48-VFQFPN footprint matches the target PCB layout constraints.

Selection Notes

Select this component when a 1:9 fan-out or multiplication from a crystal source is required for PCIe designs. Verify that the HCSL and LVCMOS output levels meet the downstream receiver specifications. Ensure the 0°C to 70°C commercial temperature range satisfies the environmental requirements of the final assembly.

Part Context

This part belongs to the Renesas clock generator family tailored for high-speed serial interfaces. It serves as a timing solution for systems requiring stable clock distribution derived from a single crystal reference, specifically optimized for PCI Express standards.

Replacement Considerations

Check for pin-compatible alternatives within the same Renesas portfolio if availability is limited. Ensure any substitute maintains the 1:9 ratio, 100 MHz capability, and compatible output voltage levels.
