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 100k
Ω
)
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 100k
Ω
)
externally to avoid the floating state.
