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.
