4-port/8-port USB 3.0 PCI Express Card with 4 Independent Host Controllers

Features

AX92321

Introduction

The AX92321 has 4-port and 8-port versions for users to choose from for various applications. The 4-port AX92321 has four independent Renesas μPD720202 USB

3.0 host controllers to offer up to 5 Gbps bandwidth per port-even when four ports are used simultaneously. The AX92321 can be configured to support maximum

of 900mA or 1500mA current output to supply stable power for various external USB devices. The AX92321 also supports power on/off control for each port

via software settings. This USB 3.0 PCI Express card is able to operate under a wide operating temperature range of 0°C to 70°C, allowing it to be used in harsh

environments for vision and factory automation applications.
