- AVSS, DVSS, HVSS and PVSS of the AK4368 should be distributed separately from the ground of external
- Do not let digital input pins float.
- When the AK4368 is in EXT mode (PMPLL bit = “0”), a resistor and capacitor for the VCOC pin is not needed.
- When the AK4368 is in PLL mode (PMPLL bit = “1”), a resistor and capacitor for the VCOC pin is shown in
Table 1.
- When the AK4368 is used in master mode, LRCK and BICK pins are floating before the M/S bit is changed to
controllers.
Note 26. Type 1-4 frequency is indicated in Table 2.
“1”. Therefore, a 100kΩ pull-up resistor should be connected to the LRCK and BICK pins of the AK4368.
