Nintendo GameCube Digital AV Connector
The DigitalAV connector carries digital sound and digital component video. Neither signal is useful by itself; the Nintendo component cable converts the digital to analogue component, and a chip is required to convert the digital audio to a usable format (TOSlink, etc). Special thanks to Oscar for this information.
Caveats
- Most GameCubes have the digital connector, however to reduce costs Nintendo removed the port from newer systems. Nintendo will add the port to your GameCube if you call and ask them about it.
- The GameCube is capable of creating a progressive signal, however the software must support it. No PAL software utilizes the progressive capability of the hardware (so no VGA either).

The Chip
This is the chip used in the official Nintendo component cables. It's made by Macronix, but is only made for Nintendo and Macronix won't divulge its secrets. The image below shows a cable with the RGB mod applied, hence the RGB select wire on pin 12, and the H/V Sync on pins 21 + 22.
