9FGL0441CKILF

Overview

The 9FGL0441CKILF is a clock generator and distribution IC from Renesas Electronics, designed for PCI Express applications. It features a single input driving four differential outputs with an input-to-output ratio of 1:4. The device operates on a 3.3V supply voltage and supports maximum frequencies up to 100MHz. It utilizes Low Power HCSL (LP-HCSL) signaling for differential outputs and LVCMOS for single-ended outputs. The component is housed in a 32-VFQFPN package with exposed pads, measuring 5x5 mm, and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Four differential LP-HCSL outputs with 100-ohm impedance
• Integrated PLL for frequency generation
• Supports PCIe Gen1 through Gen6 jitter compliance
• Spread spectrum capability for EMI reduction

Applications

• PCI Express clock distribution
• Server and storage system timing
• High-speed interface clocking

Part Context

This part belongs to the 9FGL04xx series of low-power PCIe clock generators. It serves as a replacement or upgrade for older generations like the 9FGV0441, offering support for higher PCIe speeds and improved power efficiency while maintaining compatibility with standard crystal inputs.

Replacement Considerations

Verify pinout compatibility with existing designs when replacing legacy parts like the 9FGV0441. Ensure that the 3.3V supply requirement matches the target board's power rails, as lower voltage variants exist in the family.
