PCB with BU3616K DAC for encoding 24bit RGB to analogue RGB. Used for modding 3DO for RGB. Can also be used for any device which has 24bit digital RGB. Contains a LM1881 sync stripper for obtaining CSYNC from CVBS or Luma.

BOM

IC1 - BU3616K IC2 - LM1881 C1 - C4 (100nF 0603) C5 - C6 optional(100nF 0603) C7 - C9 (220uF 1411) R1 - (1K Ohm 0603) R2 - R4 (75 Ohm 0603) R5 - (680K Ohm 0603) R6 - (75 Ohm 0603) R7 - (480 Ohm 0603)

C5 - C6 are optional power decoupling capacitors in case power source is noisy. For best results use analogue power source.

Jumper can be used to select between using Luma as sync source or pure CSYNC. Useful if there is already a sync stripper present in RGB cable.

Jumper Settings

1-2 CSYNC 2-3 Luma

3DO RGB Encoder using BU3616K IC.

This is a prototype board for obtaining analogue RGB signals from 3DO console (or any console which has 24bit RGB but no analogue RGB out). This TEST board is working and maybe useful for installs which already have 220uF coupling capacitors in the RGB cable.
