Hello support team.
I want to know if it is possible to make a point to multipoint connection with the I2S interface.
According to the diagram below, I intend to use three ADAU1979 A/D converters with I2S outputs as masters.
I intend to share the ADAU1979 outputs with three ADAU1467 audio processors.
The two conjugated I2S output channels of each ADAU1979 will be connected to the I2S inputs of the ADAU1467 that will operate as an I2S slave:
1 - the BCLK bit clock of ADAU1979 goes into the BCLK_INx pin of ADAU1467;
2 - ADAU1979's LRCLK frame sync enters ADAU1467's LRCLK_INx pin;
3 - the SDATAOUT1 data output of the ADAU1979 enters the SDATA_INx pin of the ADAU1467;
4 - the SDATAOUT2 data output of the ADAU1979 enters the SDATAIOx pin of the ADAU1467 which will be configured as an input and uses the same synchronism as SDATA_INx.
