Video driver thoughts
Re: Video driver thoughts
Well done Chris, Is there any further testing you'd like us to carry out with the current board? or should we now wait for the next revision?
If it ain't broke, test it to Destruction.

You could try adding the 75R resistors in series with the RGB lines and the 47pF caps to see if it makes any difference in video quality at all. ( Note that you may well have 33R already in series).

Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~

Re: Video driver thoughts
BTW - 50pF can also be 47pF is the value is hard to find. I've not looked for any of the parts yet...

Re: Video driver thoughts
The STV8438CV chip does seem to be very hard to find with Google and non-existent on Mouser.
