85104AGILFT

Overview

The 85104AGILFT is a clock fanout buffer manufactured by Renesas Electronics Corporation. It features a single circuit with a 1:4 input-to-output ratio, designed for high-speed signal distribution in CPU and PCI Express (PCIe) applications. The device accepts HCSL differential inputs and provides four differential LVPECL outputs. It operates within a supply voltage range of 3.135V to 3.465V and supports maximum frequencies up to 700MHz. The component is housed in a 20-VFQFN package with exposed pads, suitable for surface mount installation.
