Overview

The 9FGV0441AKLF is a low-power, 4-output PCI Express (PCIe) clock generator designed for PCIe Gen1 through Gen4 standards. It operates from a 1.8V supply and features integrated terminations for 100 ohm differential impedance, significantly reducing the bill of materials and board space. This device uses a 25MHz external crystal to provide five HCSL/LVCMOS outputs with programmable slew rates and spread spectrum capabilities.

Why Choose This Part

The 9FGV0441AKLF features integrated 100 ohm terminations which eliminate the need for up to 16 external resistors on the output lines. Its low-power 1.8V core draws as little as 32-38mA during 100MHz operation, while programmable spread spectrum options help engineers pass EMI compliance testing.

Applications

PCIe Storage Systems
Generating high-stability clock signals for NVMe SSD controllers and enterprise storage arrays.
Computing Servers
Distributing low-jitter PCIe reference clocks to expansion slots and motherboards in data center environments.
Network Interface Cards
Providing the synchronous reference clock required for high-speed Ethernet controllers.
Embedded Computing
Used in industrial PC and COM Express modules where low power consumption and small footprint are critical.

Getting Started

Engineers should provide a 25MHz crystal at the input and configure the device using strapping pins for standalone operation or via the 3.3V-tolerant SMBus interface for software-defined control. The 32-VFQFPN package requires careful attention to the thermal pad grounding to ensure signal integrity at high frequencies.
