PLL Mode (AIN3 bit = “0”, PMPLL bit = “1”)
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 5, whenever the AK4648 is supplied to stable clocks after
PLL is powered-up (PMPLL bit = “0”
→
“1”) or sampling frequency changes. When AIN3 bit = “1”, the PLL is not
available.
