Hi It’s not real clear what the second chip on the board does. If it is just a bit to Ethernet converter then you are dealing with 2 bit data out of each of the four channels. You aren’t just doing tracking in that case ….4 channels at 2 bits -> 8 bits per clock. Clock at 38 to 100 MHz. That could turn out to be a very crowded Ethernet connection.
