If i use ddc only, can i leave txclk unconnected?
Hello Victor,
It is not a good practice to leave pins unconnected, as there is an ESD structure for each pin. They should be connected to GND, or through a series resistor to 3.3v IO power.
I suggest connecting unused pins (not RESETB - this must be connected to Power-OK), to GND.
