SYSTEM DESIGN  
Figure 108 shows the system connection diagram for the AK4671. The evaluation board [AKD4671] demonstrates the  
optimum layout, power supply arrangements and measurement results.

Notes:  
- VSS1, VSS2, VSS3 and VSS4 of the AK4671 should be distributed separately from the ground of external  
controllers.  
- All digital input pins should not be left floating.  
- When the AK4671 is EXT mode (PMPLL bit = “0”), a resistor and capacitor of the VCOC pin is not needed.  
- When the AK4671 is PLL mode (PMPLL bit = “1”), a resistor and capacitor of the VCOC pin is shown in Table  
4.  
- When the AK4671 is used by master mode, LRCK and BICK pins are a Hi-Z state until M/S bit becomes “1”.  
LRCK and BICK pins of the AK4671 should be pulled-down or pulled-up by the resistor (about 100kΩ)  
externally to avoid the floating state.  
- A resistor and capacitor of the VCOCBT pin is shown in Table 76.  
- After setting PDN pin = “H”, the PCM I/F clock pins of AK4671 are a Hi-Z state until PMPCM bit becomes  
“1”. The PCM I/F clock pins of master mode should be pulled-down or pulled-up by the resistor (about 100kΩ)  
externally to avoid the floating state.
