9DB633AGLFT

Overview

The Renesas Electronics 9DB633AGLFT is a PCI Express (PCIe) zero-delay fanout buffer IC designed for clock distribution. It features one input and six outputs, supporting a maximum frequency of 110 MHz. The device operates within a supply voltage range of 3.135 V to 3.465 V and utilizes HCSL output signaling. Packaged in a 28-TSSOP form factor, it functions reliably across an operating temperature range of 0°C to +70°C. This component serves as a dedicated clock driver for PCIe applications, ensuring signal integrity through its zero-delay buffering architecture.
