9FGL0451BKILF

Overview

The Renesas 9FGL0451BKILF is a discontinued clock generator designed for PCI Express applications. It features four outputs with Low-Power HCSL signaling and a 100-ohm output impedance. The device operates on a 3.3V supply voltage within the range of 3.135V to 3.465V. It supports crystal or LVCMOS inputs and generates frequencies up to 100MHz. The component is housed in a 24-VFQFN package with exposed pads, rated for operation between -40°C and +85°C ambient temperature.

Feature Summary

• Four-output clock generation with LP-HCSL signaling
• 100-ohm differential output impedance
• Supports PCIe Gen1 through Gen6 jitter compliance
• Integrated PLL for frequency synthesis

Applications

• PCI Express (PCIe) system clock distribution
• SerDes clock generation for high-speed interfaces
• Server and storage backplane timing solutions

Procurement Notes

This part number is officially listed as End-of-Life (EOL) by Renesas Electronics. Distribution availability is restricted, and standard ordering quantities may not apply due to discontinuation status. Verification of current stock or last-time-buy options requires direct consultation with authorized distributors or the manufacturer.

Selection Notes

Designers requiring this specific configuration should verify compatibility with target PCIe generations. The fixed 100-ohm output impedance and LP-HCSL output type must match the receiving input specifications. Alternative components from the 9FGL04xx series should be evaluated for pin-to-pin compatibility and updated feature sets if available.

Part Context

The 9FGL0451BKILF belongs to the Renesas 9FGL0451 family of PCIe clock generators. This series provides low-jitter clock signals for high-speed serial data transmission. The suffix 'BKILF' denotes the specific package type, lead finish, and environmental compliance attributes associated with this variant.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Engineers should consult Renesas official documentation for recommended cross-reference devices or contact technical support for validated alternatives.
