9FGL0851CKILFT

Overview

The 9FGL0851CKILFT is a clock buffer manufactured by Renesas Electronics, designed for PCIe Gen1-5 applications. It features eight outputs and operates within a supply voltage range of 3.135 V to 3.465 V. The device supports a maximum operating temperature of +85°C and a minimum of -40°C. It is housed in a VFQFPN-48 package with surface mount installation. The component draws a typical operating current of 23 mA and maintains a duty cycle of up to 55%. This specific model variant belongs to the 9FGL0851 series.

Feature Summary

• Eight output channels for clock distribution
• Supports PCIe Gen1 through Gen5 standards
• Operates on 3.135 V to 3.465 V supply
• VFQFPN-48 package format

Applications

• PCI Express (PCIe) Gen1-5 clock generation
• Server and storage system timing
• High-speed data transmission interfaces

Procurement Notes

Verify the suffix 'CKILFT' against official Renesas documentation to confirm exact pinout and electrical characteristics, as suffixes often denote specific packaging or material compliance variations. Ensure compatibility with existing board layouts requiring the VFQFPN-48 footprint. Check for moisture sensitivity level requirements during assembly.

Selection Notes

Select this component when an eight-output clock buffer is required for PCIe Gen1-5 designs. Confirm that the 3.135 V to 3.465 V supply voltage aligns with the system power rails. Verify that the -40°C to +85°C industrial temperature range meets environmental specifications. Compare against other 9FGL0851 variants if different output counts or package types are needed.

Part Context

This part belongs to the Renesas 9FGL0851 family of ultra-low-power PCIe clock generators. The family includes variants like 9FGL0851DKILFT and 9ZXL0851EKILFT, which share similar core functionalities but may differ in specific electrical parameters, package options, or intended application nuances such as Intel QPI support.

Replacement Considerations

Direct substitutes within the same family include 9FGL0851DKILFT. Verify functional equivalence regarding output count and voltage ranges before substitution. Cross-reference datasheets for any differences in pin configurations or thermal performance.
