Projects - VGA to SCART Converter - Circuit

Finished Converter

The circuit schematic for a VGA -> SCART converter is below. You probably want to look at the introduction and notes about it too. If you want to print it out then grab the PostScript version or gschem version. This circuit was not designed by me, however I have used it myself and it works well.

The following connections should be made. The table below shows how to connect either a SCART plug (to plug directly into the TV), or a SCART socket (to plug into the TV through a standard SCART-to-SCART cable). Thanks to John Veness for pointing out I was only documenting the plug connections, even though my converter has a socket.
