PCM3168A-Q1: how to connect the audio interface of these two chips

Part Number: PCM3168A-Q1
Other Parts Discussed in Thread: PCM3168

Hi

In the audio interface (I2S or TDM) of my SOC, there are two data lines, data0 data1 (as shown in the figure below), while PCM3168 chip audio interface (I2S or TDM) has 3-4 data lines.

Please advise me how to connect the audio interface of these two chips, thank you!

  • Chen, 

    If you want all of the ADC and DAC channels on one DIN/DOUT  then the device must be configured for TDM mode, and DIN1 and DOUT1 are used. 

    For more information please refer to the Datasheet which describes this functionality. 

    best regards,
