The UFX7000 is a high performance USB 3.0 graphics adapter with multiple graphics interfaces. The
UFX7000 is an ideal solution for extending a PC workspace to an additional monitor without the need
for an additional internal graphics card. With applications ranging from docking stations, USB port
replicators, USB monitors/projectors, and embedded systems, the UFX7000 is targeted as a high
performance, low cost USB-to-graphics solution.
The UFX7000 contains integrated USB 3.0 and 2.0 Device Controllers, USB 3.0 and 2.0 PHYs, a USB
Bulk-Out Controller, Control Endpoint, Interrupt-In Endpoint, DDR2 SDRAM Controller/PHY, Graphics
Engine, HDMI/DVI Controller/PHY, Video DAC, TAP Controller, EEPROM Controller, and I
Controller.
The USB Device Controller is fully compliant with the USB 3.0 Specification, enabling the device to
operate in Super-Speed (5 Gbps) or Hi-Speed (480 Mbps) mode. Integrated USB 3.0 and 2.0 PHYs
are provided on the USB port.
The controller implements three USB endpoints: Control, Bulk-Out, and Interrupt-In. The Bulk-Out
endpoint allows for uncompressed or compressed graphics data reception from the USB port. The USB
Bulk-Out Controller collects the graphics information and transfers it to the Graphics Engine.
Implementation of vendor-specific commands allows for access to the device System Control and
Status Registers (SCSRs).
