9FGV0431AKILF

Overview

The 9FGV0431AKILF is a PCIe clock generator IC from Renesas Electronics, designed for Gen 1/2/3 applications. It features an integrated PLL and accepts a 27 MHz input to generate up to 100 MHz output frequencies. The device provides five outputs in HCSL or LVCMOS formats within a 32-lead MLF package. Operating on a single 1.8 V supply, it supports commercial temperature ranges (0°C to +70°C) with a typical operating current of 30 mA.

Feature Summary

• Integrated PLL-based clock generation supporting PCIe Gen 1/2/3 standards
• Five output channels configurable as HCSL or LVCMOS
• Accepts 27 MHz crystal input to produce up to 100 MHz frequency
• Low jitter performance with 250 ps specification

Applications

• PCI Express (PCIe) Gen 1/2/3 clock distribution systems
• Server and storage motherboard clocking architectures
• High-speed peripheral interface timing solutions

Procurement Notes

Verify the specific suffix 'AKILF' against official Renesas documentation to confirm pinout compatibility and RoHS status. Confirm that the 32-lead MLF package matches the target PCB footprint. Ensure the 0°C to +70°C commercial temperature range meets system requirements, as industrial variants may require different part numbers.

Selection Notes

Select this component when a fixed 1:5 fan-out ratio is required for PCIe designs. The 27 MHz input requirement dictates the reference oscillator choice. Verify that the 1.8 V supply voltage aligns with the system power rails. Consider the 250 ps jitter limit against the signal integrity requirements of the connected PCIe endpoints.

Part Context

This model belongs to the 9FGV0431 family of PCIe clock generators. It serves as a fixed-frequency alternative to programmable devices, simplifying design implementation for standard PCIe configurations. The 'A' suffix typically denotes specific binning or revision levels defined by the manufacturer.

Replacement Considerations

Direct replacements include other members of the 9FGV0431 series with compatible output counts and packages. Cross-reference with the 9FGV0241AKLF for lower output count options or the 9FGV0641AKILF for higher channel density, ensuring voltage and package compatibility.
