The USB 3380 is a PCI Express Gen 2 to USB 3.0 SuperSpeed Peripheral

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

compliant client port.

High Performance and Flexibility

The USB 3380 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 an existing PCI Express function (endpoint) to a USB 3.0

product. The USB 3380 can configure the PCI Express port as one x1 upstream

port or one x1 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 3380 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. The USB Duet software

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 3380 as a PCI Express endpoint include PCs,

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

main applications for the USB 3380 as a PCI Express root complex include

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

Add a USB 3.0 Client Port to PCI Express-Based Systems

The USB 3380 can be used to easily add a USB 3.0 client port to any PCI

Express based embedded system. As a PCI Express endpoint, the USB 3380’s

standard PCI Express interface connects directly to any PCI Express bus.
