2. USB3-DIO01 Board Function
2-1 Block Diagram
As shown in the figure below, in the case of USB3-DIO01, FPGA Core Logic is in charge of
overall control. The main function is to transmit Image Frame Data to the connector through the
External I/O connector. These functions are performed using API in PC through USB 3.0 interface.
The External I/O connector can be connected to the USB3-CA01 2x25 2.54Pitch Female Plug
connector by using a 2x25 2.54Pitch Male Header connector. For detailed signal specifications,
refer to Section 3-3-3.
