Figure 46. Typical Connection Diagram
Note:
- AVSS, DVSS and SVSS of the AK4633 should be distributed separately from the ground of external
controllers.
- If AVDD and DVDD are separated, DVDD should be set from 1.6V to 3.6V.
- All digital input pins should not be left floating.
- When the AK4633 is EXT mode (PMPLL bit =
0
), a resistor and capacitor of VCOC pin is not needed.
- When the AK4633 is PLL mode (PMPLL bit =
1
), a resistor and capacitor of VCOC pin is shown in
Table 36.
