9FGL04P1AKILF

Overview

The 9FGL04P1AKILF is a PCIe clock multiplexer manufactured by Renesas Electronics. It supports PCIe Gen 1 through Gen 7 standards and complies with Common Clocked (CC), Separate Reference No Spread (SRNS), and Separate Reference Independent Spread (SRIS) architectures. The device features four differential outputs using LP-HCSL signaling, operating within a frequency range of 1 MHz to 200 MHz. It accepts two HCSL differential inputs and includes selectable asynchronous or glitch-free switching modes. The component operates on a 3.3V supply voltage and is housed in a space-saving 4mm x 4mm 24-VFQFPN package.
