9FGV0641AKILFT

Overview

The Renesas 9FGV0641AKILFT is a single-circuit clock generator designed for PCI Express (PCIe) 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. Packaged in a 40-VFQFPN (5x5mm) surface-mount case, it functions across an operating temperature range of -40°C to 85°C.

Feature Summary

• Supports PCIe Gen1-4 compliant LP-HCSL outputs with integrated 100 ohm terminations
• Low power consumption with typical operation at 54 mW
• Programmable slew rate and output amplitude for line length tuning
• Selectable spread spectrum levels (0%, -0.25%, -0.5%) to reduce EMI

Applications

• PCI Express Riser Cards
• NVMe Storage Systems
• Networking Accelerators
• Industrial Control and Embedded Systems

Procurement Notes

Verify the package designation matches the 40-VFQFPN (5x5mm) specification. Confirm the input source type aligns with the LVDS or Crystal requirements. Ensure the operating environment stays within the -40°C to 85°C temperature range. Check that the system voltage remains between 1.7V and 1.9V for proper functionality.

Selection Notes

Select this component when designing for PCIe Gen1 through Gen4 interfaces requiring low power and integrated termination. The 1:7 output ratio suits systems needing multiple synchronized clocks from a single source. Consider the programmable features for optimizing signal integrity across different trace lengths and board layouts.

Part Context

This model belongs to Renesas' SOC-Friendly 1.8V Very-Low-Power PCIe clock family. It is engineered to save board space by integrating 100 ohm output terminations, eliminating the need for external resistors typically required in standard PCIe designs. The device supports zero-delay mode for precise timing alignment.
