For correct synchronization, MCLK and LRCK should be derived from the same clock signal either directly (as through a
frequency divider) or indirectly (for example, as through a DSP). The phase relationship between MCLK and LRCK
should be kept after power-up. The MCLK frequencies shown in Table 1 are supported. The internal clock frequency is
set depending on the external MCLK frequency automatically.

The AK4104 should be reset once by bringing PDN = “L” upon power-up. It takes 8 bit clock cycles for the AK4104 to
initialize after PDN pin goes “H”.
