Broadcom Inc. USB Controller USB 3382

The USB 3382 is a PCI Express Gen 2 to USB 3.0 SuperSpeed Peripheral Controller. It features two PCI Express Gen 2 x1 ports and one USB 3.0 SuperSpeed client port. The USB 3382 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 existing PCI Express functions (endpoints) to a USB 3.0 product. The internal high performance switch can configure the two PCI Express ports into one x1 upstream plus one x1 downstream, one x2 upstream, two x1 downstream, or one x2 downstream port. The flexibility allows different system configurations to achieve the maximum performance of the product. The USB 3382 provides two pairs of buffered, 100 MHz HCSL output clocks, for downstream ports (in adapter mode, one downstream port, and in root complex mode, one or two downstream ports), saving BOM cost by eliminating the need for extra clock buffer(s).
