switch
Genius 3840 points
Part Number: PCM1809


Tool/software:

Hi ti team，

  1. Does PCM1809 not need MCLK ?
  2. If necessary, which PIN should I connect to ?
  3. Do I need to directly connect PCM1809 and PDM MIC ?

    Hi,

    MCLK is only required in controller (formerly master) mode and will be supplied through the MD1 pin. Additionally, PCM1809 does not support PDM microphones only analog. A software controlled ADC such as TLV320ADCx120 supports digital microphone recording.
