I have a design where I want to connect the above devices to an FPGA. I want to connect the video bus of the two devices together. From the datasheet it seems that the ADV7612 has a 3.3V I/O and the ADV7511 has a 1.8V I/O. But the datasheet seems to indicate that the ADV7511 is 3.3V tolerant. So if I set my FPGA bank voltage to 3.3V then could I connect the two devices onto the same bus?
