Hi,
I have a board with a DSD1794A and 2 I²S sources:
- optical fiber via CS8416
- mp3 decoder (VS1053)
DSD1794A perfeclty decode I²S from CS8416 but not from VS1053. I scoped the input while VS1053 was in test mode (1kHz sine wave):
PDATA: something with (EDIT : 6.144MHz) 12.288MHz bitrate
SCK: 12.288MHz clock
PBCK: 6.144MHz clock
PLRCK: 192kHz clock
Any ideas?
EDIT:
DSD1794A accept sampling frequencies from 10 to 200kHz and sysclock from 128 to 768Fs. In my case sysclock/Fs=64, so DSD is obviously not working.
But I recently tryed to reduce Fs to 96kHz and 48kHz, keeping sysclock = 12.288MHz (ratio are 128 and 256), so DSD should work, but do not work. I really don't know what to do.
