Figure 33. Typical Connection Diagram
Notes:
- AVSS, DVSS and SVSS of the AK4536 should be distributed separately from the ground of external controllers.
- All digital input pins except pull-down pin should not be left floating.
- Value of R and C in Figure 33 should depend on system.
- When the AK4536 is EXT mode (PMPLL bit = “0”), a resistor and capacitor of VCOC pin is not needed.
- When the AK4536 is PLL mode (PMPLL bit = “1”), a resistor and capacitor of VCOC pin is shown in Table 34.
