Introduction:
The EC2380-AB is evaluation board for USB 2380-AB, an ExpressCard (PCI Express Gen 1) to USB 2.0 Hi-Speed Peripheral Controller. It features one ExpressCard (PCI Express Gen 1 x1) port and one USB 2.0Hi-Speed client port. The EC2380-AB provides a matching bandwidth at 2.5GT/s 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 system such as laptop PC with ExpressCard slot, as well as convert an existing PCI Express function (endpoint) to a USB 2.0 product. The EC2380-AB can configure the ExpressCard as one x1 upstream port or one x1 downstream port. The flexibility allows different system configurations to achieve the maximum performance of the product.
