RGB to YPbPr Converter

This is a video conversion module for the modular super gun project. It converts the typical RGB video signal generated by arcade PCBs to YPbPr also known as component video. The conversion is a simple linear process that does not introduce any conversion lag or delay.

Normally this module would be connected and would take the video signal and power from the JAMMA to Headers board, however it can be used to convert video from other sources. The video output jacks are on the front of the board while the input interface header is on the back of the board for easy mounting.

The board uses two high speeds opamps for video conversion. Depending on the opamp used the board will require a single rail (+5V for rail-to-rail opamps), or a dual rail power supply ( +/- 5V for standard opamps).

Video conversion expects a 240p capable television. The input signal must also be compatible with the NTSC standard timing and line specifications. Video from some arcade games may not convert correctly due to non-standard line count or incorrect timing.

Some arcade games generate proper video, but incorrect sync signals. A sync cleaner may require to modify the sync signal for proper conversion to take place.
