9FGV0831CKLFT

Overview

The Renesas 9FGV0831CKLFT is a clock generator IC designed for PCI Express applications. It features a single circuit with a 1:9 input-to-output ratio, supporting up to 100MHz frequency. The device accepts crystal inputs and provides HCSL and LVCMOS outputs. It operates on a 1.7V to 1.9V supply voltage within a 0°C to 70°C temperature range. Packaged in a 48-VFQFPN (6x6 mm) exposed pad surface-mount case, it integrates PLL functionality for precise timing generation.

Feature Summary

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

Applications

• PCI Express clock generation systems
• High-speed digital interface timing
• Computer peripheral clock distribution

Procurement Notes

Verify the specific suffix CKLFT against official Renesas documentation to confirm package type, temperature grade, and tape/reel specifications. Ensure compatibility with existing board layouts regarding the 48-VFQFPN footprint and pinout configuration before procurement.

Selection Notes

Select this component when a 1:9 fan-out or synthesis ratio is required for PCIe designs. Confirm that the 1.7V-1.9V supply range matches the system power rails. Verify that the 0°C to 70°C commercial temperature range meets the operational environment requirements of the target application.

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 multiple synchronized clocks derived from a single crystal reference, specifically optimized for PCIe compliance and signal integrity.

Replacement Considerations

Check for direct cross-references in Renesas' current portfolio. Verify if newer revisions of the 9FGV series offer improved electrical characteristics or updated packaging options while maintaining pin compatibility.
