Everest Semiconductor Confidential ES8311 6. DIGITAL AUDIO INTERFACEThe device provides many formats of serial audio data interface to the input of the DAC or output from the ADC through LRCK, SCLK and DSDIN or ASDOUT pins. These formats are I2S, left justified, right justified and DSP/PCM. DAC input DSDIN is sampled by the device on the rising edge of SCLK. ADC data is out at ASDOUT on the fal ing edge of SCLK. The relationship of SDATA (DSIN/ASDOUT), SCLK and LRCK with these formats are shown through Figure 2a to Figure 2d. 1 SCLK 1 SCLK LRCK L Channel R Channel SCLK SDATA MSB LSB MSB LSB Fig ure 2a I2S Serial Audio Dat a Format LRCK L Channel R Channel SCLK SDATA MSB LSB MSB LSB Fig ure 2b Left Justified Serial Audio Data For mat 1 SCLK LRCK L Channel R Channel SCLK SDATA MSB LSB MSB LSB Figure 2 c DSP/PCM Mode A Serial Audio Data Format LRCK L Channel R Channel SCLK SDATA MSB LSB MSB LSB Figur e 2d DSP/PCM M ode B Serial Audio Data Format Revision 7.0 7 January 2020 Latest datasheet: www.everest-semi.com or
