PLL Slave Mode (PMPLL bit = “1”, M/S bit = “0”)
A reference clock of PLL is selected among the input clocks to MCKI, BICK or LRCK pin. The required clock to the
AK4647 is generated by an internal PLL circuit. Input frequency is selected by PLL3-0 bits (see Table 4).
a) PLL reference clock: MCKI pin
BICK and LRCK inputs should be synchronized with MCKO output. The phase between MCKO and LRCK dose not
matter. MCKO pin outputs the frequency selected by PS1-0 bits (see Table 9) and the output is enabled by MCKO bit.
Sampling frequency can be selected by FS3-0 bits (see Table 5).
