Description
So the general idea is to take RGBS, 5V, GND, and audio in, divide 1.4v RGB to 0.7 and then run through an amp that can put out multiple signals (split)THS line, then feed one as an output, feed the other into a BH7236AF for conversion to S-Video/Composite, LM1881 can be added for sync stripping, also needed to pulse onto the Y out of the LT6550 (RGB to component). May be better to split luma from the BH7236AF to go to both svid and the component out and not worry about adding sync to the output.
