USB 3.1 10G & DisplayPort Alt-Mode PCI Express Host Card with Dual USB Type-C Receptacles (Gen2)


SUNIX UPD2018 is a Dual-port Super-Speed+ USB 3.1 10G PCI Express add-on card, and it’s compliant with the PCI Express Gen3 specification for host PC system. Based on USB Type-C pure DFP (Downstream Facing Port) mode, it works up to 10 Gbps for data transfer when connecting to USB 3.1 compliant peripherals, while maintaining compatibility with existing USB peripheral devices. USB 3.1 performance is 2 times faster than USB 3.0 and 20 times faster than USB 2.0 connectivity. In additional, one USB Type-C port supports DisplayPort Alternate-mode for video output, and the other is an USB data-only port.

With USB Type-C Receptacle, SUNIX UPD2018 supports reversible plug orientation and cable direction, which means that users will no longer need to be concerned with plug orientation/cable direction, making it easier to plug in. The new connector is smaller and thinner design, but drive higher power output capacity to USB device. SUNIX UPD2018 supports 5VDC@1500mA power output to USB device with over current protection on each USB port. This card is an ideal choice for external storage, smart phone, webcam, video devices, and all other USB electronic devices.
