Normally connected to AVSS pin with 0.1 F ceramic capacitor in parallel with a 2.2 F
electrolytic capacitor. VCOM pin goes to AVSS when PDN pin is “L”.
When at “L”, the AK4566 is in power-down mode and is held in reset. The AK4566
should always be reset upon power-up.
This clock determines which audio channel is currently being output on SDTO pin and
input on SDTI pin.
This clock is used to latch audio data.
SDTO pin goes to DVSS when PDN pin is “L”.
HPR pin goes to HVSS when PDN pin is “L”.
HPL pin goes to HVSS when PDN pin is “L”.
A capacitor for mute time constant should be connected between MUTET pin and HVSS
pin. MUTET pin goes to HVSS when PDN pin is “L”.
MOUT pin goes to Hi-Z when PDN pin is “L”.
Normally connected to AVSS pin with 0.1 F ceramic capacitor in parallel with a 4.7 F
electrolytic capacitor. VREF pin goes to AVSS when PDN pin is “L”.
