TLV320AIC3106: record and broadcast simultaneous

Part Number: TLV320AIC3106

Hello，

 One customer wanted to confirm if AIC3106 support broadcasting and recording simultaneously? That is to say, the mic input to AIC3106 and I2S output to host, at the same time the recorded audio input to AIC3106 to LEFT_LOP and RIGHT_LOP of AIC3106? 

If it is feasible, how to configure the registers?

Best regards

    Hello Kailyn,

    Thanks for reaching out. 

    Yes, this configuration is possible. All that is required is to route the path so that after the ADC the data goes to both the DAC and the I2S interface as shown below. You can use the scripts in the AIC310x GUI as a starting point for your application. See below picture of an example signal path.

    Best,
    Andrew
