SYSTEM DESIGN
Figure 45 and shows the system connection diagram for the AK4647. An evaluation board [AKD4647] is available which
demonstrates the optimum layout, power supply arrangements and measurement results.

Notes:
- AVSS, DVSS and HVSS of the AK4647 should be distributed separately from the ground of external
controllers.
- All digital input pins should not be left floating.
- When the AK4647 is EXT mode (PMPLL bit = “0”), a resistor and capacitor of VCOC pin is not needed.
- When the AK4647 is PLL mode (PMPLL bit = “1”), a resistor and capacitor of VCOC pin is shown in Table 4.
- When the AK4647 is used at master mode, LRCK and BICK pins are floating before M/S bit is changed to “1”.
Therefore, 100k
Ω
around pull-up resistor should be connected to LRCK and BICK pins of the AK4647.
