Notes:
- AVSS, DVSS and HVSS of the AK4644 should be distributed separately from the ground of external
controllers.
- All digital input pins should not be left floating.
- When the AK4644 is EXT mode (PMPLL bit = “0”), a resistor and capacitor of VCOC pin is not needed.
- When the AK4644 is PLL mode (PMPLL bit = “1”), a resistor and capacitor of VCOC pin is shown in Table 5.
- When the AK4644 is used at master mode, LRCK and BICK pins are floating before M/S bit is changed to “1”.
Therefore, 100kΩ around pull-up resistor should be connected to LRCK and BICK pins of the AK4644.
