Digital Interface Formats
The serial port operates in standard I²S, Left-justified, Right-justified (DAC only), or DSP Mode digital inter-
face formats with varying bit depths from 16 to 24. Data is clocked out of the ADC or into the DAC on the
rising edge of SCLK.
DSP Mode
In DSP Mode, the LRCK acts as a frame sync for 2 data-packed words (left and right channel) input on
SDIN and output on SDOUT. The MSB is input/output on the first SCLK rising edge after the frame sync
rising edge. The right channel immediately follows the left channel.
