EXT Slave Mode (PMPLL bit = “0”, M/S bit = “0”)
When PMPLL bit is “0”, the AK5700 becomes EXT mode. Master clock is input from MCKI pin, the internal PLL circuit
is not operated. This mode is compatible with I/F of the normal audio CODEC. The clocks required to operate are MCKI
(256fs, 512fs or 1024fs), EXLRCK (fs) and EXBCLK (
≥
32fs). The master clock (MCKI) should be synchronized with
EXLRCK. The phase between these clocks does not matter. The input frequency of MCKI is selected by FS1-0 bits (see
Table 11).

Default
The external clocks (MCKI, EXBCLK and EXLRCK) should always be present whenever the ADC is in operation
(PMADC bit = “1”). If these clocks are not provided, the AK5700 may draw excess current and it is not possible to
operate properly because utilizes dynamic refreshed logic internally. If the external clocks are not present, the ADC
should be in the power-down mode (PMADC bit = “0”).
