“rising edge” to SDO delay (Note 3)
Note: 1. If the duty of LRCK changes larger than 5% from 50%, the AK4532 is reset by the internal phase
detecting circuit automatically.
2. SCLK rising edge must not occur at the same time as LRCK edge.
3. These cycles are the number of LRCK rising from
PD
rising.
