Audio 256x/384x Clock input or output to Serial DAC. When
output, it’s generated from CS98100 internal PLL.

IEC-958 Output
This input can come from from an external comparator.
Left/Right Clock. Input from external audio ADC. The
CS98100 can be programmed to use the Audio Output func-
tion’s internally generated LR clock, in which case this pin is
not required.
samples are programmable for both input and out-
put direction.
