8.4.5 Serial audio data input format (SDIN)
• SDIN is the pin that inputs serial digital audio data such as A/D converter output.
• Data input to the SDIN can be output from the DATAO pin. The data to be input to SDIN must synchronize with
BCK and LRCK.
• Given below shows an example of a serial audio data input timing.
• Except for a special setting, we suggest the SDIN input format be consistent with the format of output data after
demodulation.
