Re: FOTH RGB combiner problems
Hi Kat, you should use a schmitt after the C1 and C2. The LS86 wants
TTL level.
I am not sure understanding your power supply. The -5V is not stabilized?
(+5V -6V3)
"Video op-amps are the way forward; component count comes down, performance improves and designing the thing gets a whole lot easier"
I don't agree. And I want the sync tips on 0V !
"Now there's an idea. I've got several flavours of RS232 line-driver in my junk box."
Do you have some MC145406 in a small smd package?
I got some from RS order code 273-270 and they are big smd's.
Kind regards
Darius
