Currently Viewing:

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 SuperSpeed client port. The USB 3380 provides a matching bandwidth at 5 GT/s 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. The USB 3380 provides a pair of buffered, 100 MHz HCSL output clocks, for the downstream port when configured in root complex mode, saving BOM cost by eliminating the need for extra clock buffer(s).
