Dek's RGB to Component Transcoder (17/5/2020) - This schematic and PCB has been designed to convert a video signal from RGB format to Component (Y,Y-r, Y-b) format. This signal is typically used for retro video game consoles and arcade boards.

Background Component video can be found in modern CRT TVs to support better picture quality from DVD players and Set Top / Cables boxes. It is found on many later model CRTs and LCD screens.
NOTE - This schematic will not upscale a 240p signal. Many LCD tvs will not display a 240p picture through Component video in!
This schematic was intended to be used for consumer CRT TVs as another way to support RGB (particulary in arcade setups where crt tubes are getting harder to find/replace). It is designed to be used as an external device (outside of the system) rather used internally.
Initial successful testing (on version VA01 19/4/2020):
Please share, clone, improve and share again (pay it forward) - that way we can all benefit. This was based on many designs found on the web using the BA7230 chip and from plenty of own my trials and testing the quality of outputs.
