So.
I want to make a component video input into my Cadet system.
The goal is to have full RGB video input instead of the single black and white luma I have now.
I think I will make 1 big pcb out of this. Or maybe 3 joined / sandwiched smaller ones… not sure yet.
Lars and Pbalj have given me some tips (see below), but I’m a bit stuck.
I have copied the layout for the video input pcb in Eagle.
The idea (I think) is to copy the sync info that is coming into the first input to the other 2 inputs.
Now I’m looking at the sync points that need pinouts. Somewhere at the LM1881?
Should the video input be RGsB or YPbPr?
Or is it already possible with 3 “vanilla” RGB inputs, by patching ?
the tips:
pbalj:
you could also get component in to cadets if you use green in to the sync, and then in to video input, as well as r and b in their own video inputs as well.
Lars:
You would need to modify the secondary units to share the sync signals generated by the first, but you could definitely use 3x Cadet IIIs to get component video (YPbPr and RGsB) into your Cadet rig!
