Introduction:
The USB 2380 is a PCI Express Gen 1 to USB 2.0 Hi-Speed Peripheral Controller. It features one PCI Express Gen 1 x1 port and one USB 2.0Hi-Speed client port. The USB 2380 provides a matching bandwidth at 2.5 GT/s between the PCI Express Gen 1 bus and the USB 2.0Hi-Speed bus. The controller can easily add a USB 2.0 client port to an existing PCI Express system, as well as convert an existing PCI Express function (endpoint) to a USB 2.0 product. The USB 2380 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.
