Overview

The 9FGV0241AKILFT is a low-power, 1.8V PhiClock PCIe clock generator designed to support PCI Express Gen1 through Gen4 requirements. It features a 1:3 input-to-output ratio, providing two HCSL outputs and one LVCMOS output from a single crystal input. The device integrates terminations to reduce component count and simplifies board design for space-constrained applications.

Why Choose This Part

This IC offers significant power savings with a typical running current of 7mA on VDDA and 15mA on VDD at 100MHz. Integrated terminations eliminate the need for external resistors on the differential HCSL outputs, saving PCB area. It also includes an SMBus interface for optional configuration and supports spread spectrum to help mitigate EMI issues.

Applications

PCIe Storage Systems
Providing the reference clock for NVMe SSDs and high-speed storage controllers requiring PCIe Gen4 compliance.
Network Interface Cards
Distributing stable 100MHz clocks to Ethernet controllers and specialized networking SoCs.
Industrial Computing
Serving as a compact clock source for embedded motherboards and single-board computers using PCIe expansion slots.
Wake-On-LAN (WOL) Support
Utilizing dedicated power management features to maintain connectivity during system sleep modes.

Getting Started

Designers should provide a 1.8V supply and a suitable 25MHz crystal for the input stage. Configuration can be handled via hardware pins or through the SMBus interface to adjust features like spread spectrum and output enables. Refer to the Renesas Timing Commander software tool for calculating register settings if using the SMBus configuration mode.
