    A customer ask me to do a Toslink/SPDIF digital audio mod for a GC. I have not done one yet but I decided to give it a go.

    I built a small PCB and sent it off to osh park:

    BOM from DigiKey:
    1x Hex Convertor - 296-8208-1-ND
    1x 12.288 Crystal - CTX266CT-ND
    1x 47uf Cap - PCE3875CT-ND
    3x .1uf Cap - 490-1532-1-ND
    1x TC9231N - Obselete part, Find on Ebay/Aliexpress etc.
    1x TX178A - Ebay etc. Really any 5v TX Toslink should work.

    I'm using some small components in this build 0603 caps and TSSOP hex

    Here is our hookup locations. This is my personal gamecube, I plan on doing the HDMI setup soon, (I'm building a new board based on the shuriken design), which is why I soldered directly to the SMD. I wanted to test on my equipment before the customers. You can trace the wires I soldered to the SMD to the Digital A/V pins. Which would be much easier solder. They pin numbers I think 22,21,19


    Here is the case modifications:


    I'm using Strong 3M double sticky foam to hold the board. in place. I would mount it in side the metal cage but the 47uf cap was too tall :-(



    The End.

    This has been discussed before somewhere. The BCK and the 12.288 MHz clock are not in sync. Back then we were wondering if this would affect the audio somehow.
