The external clocks which are required to operate the AK5392 are MCLK, LRCK(fs),SCLK. MCLK should be
synchronized with LRCK but the phase is free of care. MCLK can be either 256fs or 384fs by setting CMODE pin.
When the 384fs is selected, the internal master clock becomes 256fs(=384fs*2/3). Table 1 illustrates standard
audio word rates and corresponding frequencies used in the AK5392.
As the AK5392 includes the phase detect circuit for LRCK, the AK5392 is reset automatically when the
synchronization is out of phase by changing the clock frequencies. Therefore, the reset is only needed for power-up.
AK5392 supports four serial data formats which can be selected via SMODE1 and SMODE2 pins(Table 2 ). The
data format is MSB-first, 2's complement.
