Master Mode and Slave Mode
The M/S pin selects between master and slave modes. M/S pin = “H” is master mode, M/S pin = “L” is slave mode. In
master mode, MCKO, BICK and LRCK are output. In slave mode, only MCKO is output from the AK4584 and dividing
MCKO externally provides BICK and LRCK.

Relationship Clock operation and Power down
When the AK4584 is powered down, the XTALE pin controls the master clock output. The DMCK pin disables the
MCKO1 output.

Normal Operation
Table 18. Clock Operation
Note 1) : Since the DIR is powered down, a X’tal oscillator or the external clock can be selected for the clock source.
Note 2) : CM1-0 bits select the clock source. When changing between modes, there is a possibility
that the master clock output (MCKO) stops momentarily.
Note 3) : When PDN pin = “L”, XTI pin is fixed to “L” when XTALE pin = “L” and the external clock is not AC coupled.
Digital High Pass Filter
The ADC has a digital high-pass filter for DC offset cancellation. The cut-off frequency of the HPF is 0.9Hz at fs =
44.1kHz and also scales with sampling rate (fs).
