    Hi, Nat,

    1. Unfortunately, this connection is not possible. The TLV320AIC3204 can route the digital mic clock and data only to one pin. For example, the digital mic clock routed to the MISO pin and the data to SCLK. This is due to the internal multiplexer and demultiplexer that the codec uses to select the clock and data.

    2. However, the TLV320AIC3204 can accept two digital microphone at same time. You may take as example the figure 2-25. The digital microphones can share the same clock and data lines. One of the microphones must be used for the right channel and the second one for the left channel.

    I hope this helps you. Please let me know if you have more questions or comments.

    Best regards,
