5. DIGITAL AUDIO INTERFACE

The device provides many formats of serial audio data interface to the output from the ADC

through LRCK, SCLK and SDOUT pins. These formats are I2S, left justified, DSP/PCM mode and

TDM. ADC data is out at SDOUT on the falling edge of SCLK. The relationships of SDOUT, SCLK

and LRCK with these formats are shown through Figure 2a to Figure 2h. ES7210 can be cascaded

up to 16-ch through single I2S or TDM, please refer to the user guide for detail description.
