EXT Slave Mode (PMPLL bit = “0”, M/S bit = “0”)
When PMPLL bit is “0”, the AK5701 becomes EXT mode. Master clock is input from the 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 is not important. The input frequency of MCKI is selected by FS1-0 bits
(
Table 11
).

Table 11. MCKI Frequency at EXT Slave Mode (PMPLL bit = “0”, M/S bit = “0”) (x: Don’t care)
The external clocks (MCKI, EXBCLK and EXLRCK) should always be present whenever the ADC is in operation
(PMADL bit = “1” or PMADR bit = “1”). If these clocks are not provided, the AK5701 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 (PMADL=PMADR bits = “0”).
