9DB803DFLFT

Overview

The Renesas Electronics 9DB803DFLFT is a zero-delay clock buffer designed for PCI Express Gen2 applications. It features eight HCSL outputs driven by an HCSL input, supporting maximum frequencies up to 400 MHz. The device operates within a supply voltage range of 3.135 V to 3.465 V and draws 190 mA of operating current. Packaged in a 48-pin SSOP format, it functions reliably between 0°C and +70°C. This component provides signal distribution with minimal propagation delay for high-speed digital systems.
