ASAHI KASEI
The AK4116 has a master clock output pin, MCKO. In PLL mode, PLL lock range is up to 48kHz and the MCKO
frequency is fixed to 256fs.
In the X’tal mode, XCKS1-0 bits select the ratio of the X’tal frequency to fs (sampling frequency). The DIV bit selects
the ratio (x1 or x1/2) of the MCKO frequency to the X’tal frequency (Table 2).
