LC78815 surrounded by beautiful sticky flux residue.

The Sanyo LC78815 is a 16-bit stereo audio DAC, used in the NeoGeo CD consoles to translate serial audio data from the CD drive (and the NEO-YSA chip on some models) into analog signals.

They're located on the NEO-CDA board.

CDDA configuration: FSEL=1, MODE1=0, MODE2=1, DATAR=0.

Todo: BCLK=44100*2*24=2.116800MHz ? SYSCLK=16.934400MHz ? LRCK=44100Hz ?
