■
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.
clock frequency. MCLK frequency, SCLK frequency and master/slave are selected by CKS2-0 pins as shown in
All external clocks (MCLK, SCLK and LRCK) must be present unless PDN pin = “L”. If these clocks are not provided,
the AK5358A may draw excess current due to its use of internal dynamically refreshed logic. If the external clocks are not
present, place the AK5358A in power-down mode (PDN pin = “L”). In master mode, the master clock (MCLK) must be
provided unless PDN pin = “L”.
Note 15. SDTO outputs 16bit data at SCLK=32fs.
