Notes:
- AVSS, DVSS and HVSS of the AK4642 should be distributed separately from the ground of external
controllers.
- All digital input pins should not be left floating.
- When the AK4642 is EXT mode (PMPLL bit = “0”), a resistor and capacitor of VCOC pin is not needed.
- When the AK4642 is PLL mode (PMPLL bit = “1”), a resistor and capacitor of VCOC pin is shown in Table 4.
- When piezo speaker is used, 2.6
5.25V power should be supplied to HVDD and 10
or more series resistors
should be connected to both SPP and SPN pins, respectively.
- When the AK4642 is used at master mode, LRCK and BICK pins are floating before M/S bit is changed to “1”.
Therefore, 100k
around pull-up resistor should be connected to LRCK and BICK pins of the AK4642.
