The USB 2380 is a PCI Express Gen 1 (2.5Gbps) to USB 2.0 Hi-Speed

Peripheral Controller. It features one PCI Express Gen 1 x1 port and one

USB 2.0-compliant client port.

High Performance and Flexibility

The USB 2380 provides 480Mbps bandwidth between the

PCI Express Gen 1 bus and the USB 2.0 Hi-Speed bus. The controller can easily

add a USB 2.0 client port to an existing PCI Express system. The USB 2380’s

standard PCI Express interface provides a x1 upstream port to connect directly to

any PCI Express downstream port for 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 2380 can be used with existing NET 2280/2282 software

with no 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 480Mbps of transfer speed with just a

simple USB cable.

Applications

Target applications for the USB 2380 as a PCI Express endpoint include PCs,

servers, set-top boxes (STBs), digital video recorders (DVRs), printers, and PCI

Express embedded systems.

Add a USB 2.0 Client Port to PCI Express-Based Systems

The USB 2380 can be used to easily add a USB 2.0 client port to any PCI

Express based embedded system. As a PCI Express endpoint, the USB 2380’s

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