The USB 3382 is a PCI Express Gen 2 to USB 3.0 SuperSpeed Peripheral

Controller. It features two PCI Express Gen 2 x1 ports and one USB 3.0-

compliant client port.

High Performance and Flexibility

The USB 3382 provides a matching bandwidth at 5 GTps

between the PCI Express Gen 2 bus and the USB 3.0

SuperSpeed bus. The controller can easily add a USB 3.0 client port to an

existing PCI Express system, as well as convert existing PCI Express functions

(endpoints) to a USB 3.0 product. The internal high performance switch can

configure the two PCI Express ports into one x1 upstream + one x1 downstream,

one x2 upstream, two x1 downstream, or one x2 downstream port. The

flexibility allows different system configurations to achieve the maximum

performance of the product.

Abundant Software

As the successor of the gold standard NET 2280, PCI to USB 2.0 peripheral

controller, the USB 3382 can be used with existing NET 2280 software with no

or minimal change. Driver stacks are already available in common OS’s such as

Windows (XP, Vista, 7 and CE), Linux, and VxWorks. USB Duet software from

PLX will provide the fastest PC interconnect at 400 mega bytes per second of

transfer speed with just a simple USB cable.

Applications

Target applications for the USB 3382 as a PCI Express endpoint include PCs,

servers, docking stations, printers, and PCI Express embedded systems. The

main applications for the USB 3382 as a PCI Express root complex include

WLAN dongles, graphics/video dongles, and HDTV tuners/codec.
