9FGV0231AKILF

Overview

The 9FGV0231AKILF is a low-power PCI Express (PCIe) clock synthesizer manufactured by Renesas Electronics. It integrates a Phase-Locked Loop (PLL) to generate precise clock signals for PCIe Gen1, Gen2, and Gen3 applications. The device accepts an input frequency up to 27 MHz and produces three outputs at a maximum frequency of 100 MHz. It operates on a single 1.8 V supply with a typical current consumption of 15 mA. The component is housed in a compact 24-VFQFPN package with exposed pads, suitable for surface-mount assembly.

Feature Summary

• Integrated PLL synthesizer supporting PCIe Gen1/Gen2/Gen3 standards
• Three output channels with HCSL or LVCMOS logic levels
• Low power consumption of 15 mA at 1.8 V supply voltage
• Input frequency range up to 27 MHz with max output of 100 MHz

Applications

• PCI Express root complex clock generation
• PCI Express switch clock distribution
• High-speed digital interface timing synchronization

Procurement Notes

Verify the suffix 'KILF' corresponds to the lead-free RoHS-compliant variant in tube packaging. Confirm the operating temperature grade matches the design requirement, as industrial versions typically support -40°C to +85°C. Ensure the 24-VFQFPN footprint aligns with the PCB layout specifications before procurement.

Selection Notes

Select this model when a single-input, three-output clock solution is required for PCIe architectures. The device supports crystal inputs and offers flexible output configurations via HCSL or LVCMOS. Verify that the 1.8 V supply voltage meets the system power constraints and that the 100 MHz maximum frequency covers the target PCIe link speed requirements.

Part Context

This component belongs to the 9FGV0231 family of low-power PCIe clock generators. It serves as a direct replacement for legacy ICS9FGV0231 devices. The part is designed to reduce power consumption in high-density server and storage systems while maintaining signal integrity for multi-gigabit data transfers.

Replacement Considerations

Check pin-to-pin compatibility with existing designs using the ICS9FGV0231. Verify that the output drive strength and load capacitance requirements are met by the HCSL/LVCMOS outputs. Ensure the thermal performance of the 24-VFQFPN package is adequate for the application environment.
