9FGL0451CKILFT Description

Short technical summary and product information.

The Renesas 9FGL0451CKILFT is an application-specific clock generator IC designed for PCI Express (PCIe) systems. It accepts a clock or crystal input and generates a 100MHz output with a 1:2 fanout ratio. The device supports both HCSL and LVCMOS output types, making it suitable for driving PCIe reference clocks and other high-speed digital logic.

 

This clock generator operates from a 3.135V to 3.465V supply voltage and is specified over an industrial temperature range of -40°C to +85°C. It integrates a phase-locked loop (PLL) for jitter cleaning and frequency synthesis. The part is housed in a compact 24-VFQFN exposed pad package (24-QFN, 4x4mm) for surface mount assembly.

 

Typical applications include PCIe clock distribution in servers, storage systems, networking equipment, and embedded computing platforms. The 1:2 fanout allows a single input to drive two output loads, simplifying clock tree design.
