Axiomtek AX92321-8U 8 Port PCIe USB 3.0 Card with 4x Renesas μPD720202 Independent Host Controllers

Some vision and automation systems connect many USB 3.0 devices, such as cameras, scanners and instruments, to one PC and run out of ports. The AX92321-8U is the eight-port build in the Axiomtek AX92321 series, a USB 3.0 PCIe card that Axiomtek positions for vision and factory automation. We specify it for customer systems and fit it to the machines we build.

The card carries eight USB 3.0 Type A ports served by four Renesas uPD720202 host controllers, compliant with USB 3.0 and Intel xHCI revision 1.0. Ports support SuperSpeed (5 Gbps), high speed (480 Mbps), full speed (12 Mbps) and low speed (1.5 Mbps). The host interface is PCI Express x4 Gen2. Axiomtek quotes the per-port rate with all ports busy only for the four-port card, so we plan bandwidth with you when several high-rate devices share this card.

Output current is jumper-set per port at 900 mA or 1500 mA maximum, and each port’s power can be switched on or off in software for remote resets. If every device needs its own controller, the AX92321-4U gives four ports with one controller each. For Gigabit network cameras, the AX92322-4GbE offers four Ethernet ports instead.

The card draws power from the PCIe slot, with up to 20 W of total USB power output, or from the 6-pin ATX connector (5 A at 12 V or 2.5 A at 24 V) or 4-pin Molex connector (5 A at 12 V). It operates from 0 to +70 °C and stores from -20 to +80 °C. The board measures 168 x 107 mm, carries CE compliance and supports Windows 7/10 (32/64-bit) and Ubuntu 20.04 LTS.
