3.8. Hardware Setup

The HDMI Intel® FPGA IP design example is HDMI 2.0b capable and performs a loop-through demonstration for a standard HDMI video stream.
To run the hardware test, connect an HDMI-enabled device—such as a graphics card with HDMI interface—to the Transceiver Native PHY RX block, and the HDMI sink input.
  1. The HDMI sink decodes the port into a standard video stream and sends it to the clock recovery core.
  2. The HDMI RX core decodes the video, auxiliary, and audio data to be looped back in parallel to the HDMI TX core through the DCFIFO.
  3. The HDMI source port of the FMC daughter card transmits the image to a monitor.
Note: If you want to use another Intel FPGA development board, you must change the device assignments and the pin assignments. The transceiver analog setting is tested for the Intel® Stratix® 10 FPGA development kit and Bitec HDMI FMC 2.0 daughter card. You may modify the settings for your own board.
