9DBU0941AKILF

Overview

The 9DBU0941AKILF is a PCIe fanout clock buffer manufactured by Renesas Electronics Corporation. It features a 1:9 input-to-output ratio, converting one differential HCSL or LVDS input into nine differential LP-HCSL outputs. The device operates at a maximum frequency of 167 MHz with a supply voltage range of 1.425V to 1.575V. It is housed in a 48-VFQFN package with an exposed pad and supports surface mount installation. The component functions without an internal PLL and is designed for common temperature applications.
