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
AK4671 is generated by an internal PLL circuit. Input frequency is selected by PLL3-0 bits (
Table 4
).
a) PLL reference clock: MCKI pin
BICK and LRCK inputs should be synchronized with MCKO output. The phase between MCKO and LRCK does not
matter. The MCKO pin outputs the frequency selected by PS1-0 bits (
Table 9
) and the output is enabled by MCKO bit.
Sampling frequency can be selected by FS3-0 bits (
Table 5
).
In case that the CODEC is used without Audio I/F (like phone call), the CODEC can be operated by MCKI only. In this
case, BICK and LRCK can be stopped.
