Internal Reset Function for Clock Change
The AK4127 is reset automatically when the output clock is stopped. If the output clock is started again, normal data is
output within 100ms.
Sequence of Changing Clocks
The change sequence of the clock supplied to AK4127 is shown in Figure 17

Figure 17. Sequence of changing clocks
Note 1. The data on SDTO may cause a clicking noise. To prevent this, set “0” to the SDTI from GD before the PDN
pin changes to “L”. It makes the data on SDTO remain as “0”.
Note 2. SMUTE can also be used to remove the unknown data.
UNLOCK pin
The UNLOCK pin outputs “L” when the internal PLL is locked. When the internal PLL is unlocked, the UNLOCK pin
outputs “H” and the SDTO = “0”. When the PDN pin = “L”, the UNLOCK pin outputs “H”.
