External MIC
Notes:
Internal MIC
- AVSS and DVSS of the AK5701 should be distributed separately from the ground of external controllers.
- All digital input pins should not be left floating.
- When the AK5701 is EXT mode (PMPLL bit = “0”), a resistor and capacitor of the VCOC pin is not needed.
- When the AK5701 is PLL mode (PMPLL bit = “1”), a resistor and capacitor of the VCOC pin is shown in
- Mic input AC coupling capacitor should be 1μF or less to start the recording within 100ms.
4. 0.1 x Cp in parallel with Cp+Rp improves PLL jitter characteristics.
