1.3. Schematic Diagrams
Using HDMI 2.0 link topology requires you to meet the 3.3 V electrical compliance. To meet the 3.3 V compliance on Intel FPGA devices, you need to use a level shifter. Use a DC-coupled redriver or retimer as the level shifter for the transmitter and receiver.
The external vendor devices are TMDS181 and TDP158RSBT, both running on DC-coupled links. You need a proper pull-up at CEC lines to ensure functionality when inter-operating with other consumer remote control devices.
The Bitec schematic diagrams are CTS-certified. Certification is, however, product level specific. Platform designers are advised to certify the final product for proper functionality.
