[3] External Digital Filter Mode (EX DF I/F Mode)
DW indicates the number of BCK in one WCK cycle. The audio data is input by MCLK, BCK and WCK from the DINL
and DINR pins. Three formats are available
BCK. The BCK and MCLK clocks must be the same frequency and must not burst. BCK and MCLK frequencies for each
sampling speed are shown in
The AK4392 is automatically placed in reset state when MCLK and WCK are stopped during a normal operation (PDN
pin =“H”), and the analog output becomes Hi-Z. When MCLK and WCK are input again, the AK4392 exit reset state and
starts the operation. After exiting system reset (PDN pin =“L”→“H”) at power-up and other situations, the AK4392 is in
power-down mode until MCLK and WCK are supplied.
