9FGV0641AKLFT

Overview

The 9FGV0641AKLFT is a single-circuit clock generator and PLL frequency synthesizer manufactured by Renesas Electronics Corporation. Designed for PCI Express applications, it operates within a supply voltage range of 1.7V to 1.9V and supports a maximum frequency of 100MHz. The device accepts LVDS or crystal inputs and provides HCSL and LVCMOS outputs in a 1:7 ratio. It is housed in a 40-VFQFPN package with dimensions of 5.00x5.00x0.90 mm and an exposed pad, suitable for surface mount assembly.

Feature Summary

• Single circuit configuration with PLL support for PCI Express timing
• Operates on 1.7V to 1.9V supply voltage with 100MHz max frequency
• Accepts LVDS or Crystal input signals
• Provides HCSL and LVCMOS output signaling types

Applications

• PCI Express (PCIe) system clock generation
• Application specific clock and timing circuits

Procurement Notes

Verify the package designation matches the 40-VFQFPN (5x5) specification with 0.40mm pitch. Confirm the operating temperature range is 0°C to 70°C (TA) for the specific batch. Ensure the supplier-device-package aligns with the required surface mount footprint for PCB layout compatibility.

Selection Notes

Select this component when a single-clock solution for PCIe is required with low voltage operation between 1.7V and 1.9V. The 1:7 output ratio accommodates multiple downstream loads from one source. Verify that the HCSL and LVCMOS output levels meet the interface requirements of the target logic devices.

Part Context

This part belongs to the Application Specific Clock/Timing category under Renesas Electronics Corporation. It serves as a dedicated clock generator for high-speed serial interfaces, specifically optimized for PCI Express standards. The device integrates phase-locked loop functionality to synthesize precise clock frequencies from reference inputs.

Replacement Considerations

Check for compatible single-circuit PCIe clock generators with matching 1.7V-1.9V supply ranges and 40-pin VFQFPN packages. Ensure replacement parts support both LVDS and crystal inputs with HCSL/LVCMOS outputs at 100MHz.
