Function
Digital Ground Pin
Digital Power Supply Pin, 3.3V or 5.0V
Master Clock Input Pin
Power-Down Mode Pin
When at “L”, the AK4396 is in power-down mode and is held in reset.
The AK4396 should always be reset upon power-up.
Audio Serial Data Clock Pin in PCM mode
DSD Clock Pin in DSD mode
Audio Serial Data Input Pin in PCM mode
DSD Lch Data Input Pin in DSD mode
L/R Clock Pin in PCM mode
DSD Rch Data Input Pin in DSD mode
Soft Mute Pin in parallel mode
When this pin goes “H”, soft mute cycle is initiated.
When returning “L”, the output mute releases.
Chip Select Pin in serial mode
Sampling Speed Mode Select Pin in parallel mode (Internal pull-down pin)
Chip Address 0 Pin in serial mode
(Internal pull-down pin)
De-emphasis Enable 0 Pin in parallel mode
