Avago USB338x PCIe to USB 3.0 Peripheral Controller

Avago USB 338x is a PCI Express Gen 2 to USB 3.0 SuperSpeed Peripheral Controller. It features one or two PCI Express Gen 2 x1 ports and one USB 3.0 SuperSpeed client port. The USB 338x 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 USB 3382 provides one or two pairs of buffered, 100 MHz HCSL output clocks, for downstream ports, eliminating the need for extra clock buffer(s).
