PLL Mode
When PMPLL bit is “1”, a fully integrated analog phase locked loop (PLL) generates a clock that is selected by the
PLL3-0 and FS3-0 bits. The PLL lock time is shown in Table 4, whenever the AK4647 is supplied to a stable clocks after
PLL is powered-up (PMPLL bit = “0”
→
“1”) or sampling frequency changes.

Table 5. Setting of Sampling Frequency at PMPLL bit = “1” (Reference Clock = MCKI pin)
When PLL reference clock input is LRCK or BICK pin the sampling frequency is selected by FS3 and FS1-0 bits. (See
