CompactPCI® Serial • 16-Port USB 3.0 SuperSpeed Controller

The SBX-DUB is a peripheral slot board for PICMG® CompactPCI® Serial systems, equipped with four individual quad port USB 3.0 controllers, providing a total of 16 USB xHCI SuperSpeed channels. 12 USB 3.0 ports are available for rear I/O via the backplane connectors P3/P4. At the users choice, another set of 4 channels can be directed either to the USB 3.0 front panel receptacles, or can be used via rear I/O. Since any front panel connector is assigned to a separate SuperSpeed controller, a superior throughput can be achieved in total. The SBX-DUB is provided with a PCI Express® 2.0 package switch for a PCIe x 4 uplink to the host, and can be installed into any peripheral slot of a CompactPCI® Serial backplane. A single PCIe lane would be sufficient for typical operation, but the optimum performance will be achieved when the SBX-DUB is inserted into a CompactPCI® Serial fat pipe slot, or an ordinary CompactPCI® Serial peripheral slot with support for PCIe x 4.
Suitable rear I/O modules (e.g. SBR-RIO) are available in addition to the SXB-DUB.
