NEO-CDA3-1
Carries a YM3016 DAC, LC78815 CDDA DAC, 2 quad op-amps, a CXA1645 video encoder, 2 7805 regulators, a LM2930 8V regulator and various transistors.
Connectors, from left to right (need exact pinouts):
- YM2610 to YM3016 serial data
- CDDA left, right, clock
- RGB video and sync
- CD 5V, 10V CD, 5V logic, Ground
NEO-CDA4-1
Same as the NEO-CDA3-1, but with only one dual op-amp and a second LC78815 instead of the YM3016 (which isn't needed anymore with boards using the NEO-YSA chip, capable of outputting LC78815 compatible serial streams).
24M08 regulator instead of the LM2930 ?
Connectors, from left to right (need exact pinouts):
- CDDA left, right, clock
- NEO-YSA left, right, clock
- RGB video and sync
- CD 5V, 10V CD, 5V logic, Ground
