9FGV0631CKLFT

Overview

The Renesas 9FGV0631CKLFT is a clock generator IC designed for PCI Express applications. It features one circuit with a 1:6 input-to-output ratio, supporting LVDS or crystal inputs and LP-HCSL or LVCMOS outputs. The device operates at a maximum frequency of 100 MHz with a supply voltage range of 1.7 V to 1.9 V. It is housed in a 40-VFQFPN (5x5 mm) package with an exposed pad and functions within a temperature range of 0°C to 70°C.

Feature Summary

• PCIe-specific clock generation with 1:6 fan-out capability
• Supports LVDS and Crystal inputs with LP-HCSL and LVCMOS outputs
• Operates on a 1.7 V to 1.9 V power supply
• Integrated PLL for precise clock synthesis

Applications

• PCI Express system clock distribution
• High-speed digital interface timing
• Computer motherboard clock generation

Procurement Notes

Verify the operating temperature grade matches the design requirements, as this specific suffix indicates a commercial range of 0°C to 70°C. Confirm the package dimensions align with the PCB footprint, specifically the 40-VFQFPN exposed pad configuration. Ensure the supply voltage constraints are strictly maintained within the 1.7 V to 1.9 V window for proper operation.

Selection Notes

Select this component when a dedicated PCIe clock generator with six outputs is required. It is suitable for designs needing LP-HCSL or LVCMOS output levels derived from LVDS or crystal sources. Consider the commercial temperature range limitation if the application environment exceeds 70°C. Verify that the 100 MHz maximum frequency meets the target bus speed requirements.

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 reference source. The device integrates phase-locked loop functionality to minimize jitter and ensure signal integrity across the six output channels.

Replacement Considerations

Check for updated revisions within the same series that may offer extended temperature ranges or alternative packaging options. Verify pin compatibility if substituting with other 40-pin VFQFPN clock generators. Ensure any replacement maintains the 1:6 ratio and supports the required input/output voltage levels.
