ADC Operating Modes
Nodes:
-
There are 16bit presented at SDO at each cycle but just the first 14 do have relevalt data.
-
The ADC is a single channel (mono) path. The same SDO bitstream is presented for left and right channel of one cycle.
-
The ADC sampling rate is equal to LRCK/4. This means that the SDO bitstream gets updated at each 4th cycle of LRCK.
-
SCLK has to have at least 34 cycles within one LRCK cycle
2*(16bit data + the leading empty bit)
