MCLK, SCLK and LRCK (fs) clocks are required in slave mode. The LRCK clock input must be synchronized with
MCLK, however the phase is not critical. Table 1 shows the relationship of typical sampling frequency and the system
clock frequency. MCLK frequency, SCLK frequency, HPF (ON or OFF) and master/slave are selected by CKS2-0 pins as
shown in Table 3. When MCLK is 192fs, 384fs or 768fs, the sampling frequency does not support variable pitch.
All external clocks (MCLK, SCLK and LRCK) must be present unless PDN pin = “L”. If these clocks are not provided,
the AK5386 may draw excess current due to its use of internal dynamically refreshed logic. If the external clocks are not
present, place the AK5386 in power-down mode (PDN pin = “L”). In master mode, the master clock (MCLK) must be
provided unless PDN pin = “L”.
Note 13. SDTO outputs 16bit data at SCLK=32fs.
