The first 2 modules seem to work quite well now. It helped to put 75Ohm resistors in parallel at the outputs of the MAX457 op-amp, to stop it from oscillating. Maybe we should also put a resistor in series as Max has seen on the datasheet? \ud83d\ude09<\/p>\n

Anyway, the picture quality seems better that expected and we’re really pleased.<\/p>\n

These are the only modules we’ve built this far, so the only thing we can do is connect them and measure the quality of the output picture. But we’re getting really excited and can’t help to just try to put some stuff in the signal path. Here’s the results with<\/p>\n
