USB 3.0 SuperSpeed Controller

The CB3-TONE is a CompacPCI® peripheral card, equipped with a PCI Express® to USB 3.0 quad-port controller. Four USB 3.0 receptacles are available via the front panel for attachment of external USB 3.0 and USB 2.0 compliant devices. Electronic power switches are provided, for up to +5V/1.5A load at any USB connector.

The USB controller supports all data transfer protocols on any connector, SuperSpeed (USB 3.0 xHCI) as well as high-speed, full-speed, and low-speed. The CB3-TONE is provided with a PCI® to PCI Express® bridge, as interface between the USB controller and the CompacPCI® backplane.

CB3-TONE - USB 3.0 SuperSpeed for CompactPCI®

The CB3-TONE is equipped with the TI TUSB7340 single chip PCI Express® to USB 3.0 bridge. The xHCI (SuperSpeed) compliant host controller supports up to four downstream ports. Each downstream port may be independently enabled and has individual power control and overcurrent detection.

SuperSpeed USB 3.0 offers ten times the data speed of USB 2.0 (5 Gbit/s compared to 480 Mbit/s). The bandwidth of the xHCI controller is shared over all TUSB7340 downstream ports. Texas Instruments provides xHCI compliant Windows® drivers for download.

As with any CompactPCI® Classic peripheral card, the backplane bandwidth is the limiting parameter if performance is discussed. Up to ~2Gbps data throughput is available across a 32-bit CompactPCI® backplane @66MHz. The data rate of a SuperSpeed USB port however is rated at 5Gbps. As a result, the maximum performance which can be achieved with the CB3-TONE is significantly higher than with previous USB 2.0 solutions, but considerably below the USB 3.0 maximum. Beyond the bandwidth discussion, the CB3-TONE is a reliable and economic USB 3.0 controller card, which can be simply integrated in any industrial CompactPCI® system.
