TLV320AIC3109-Q1: TLV320AIC3109

Dear Sir,

I found Reg26 AGC Decay Time is from 100~500ms, but in 7.3.3.2.2.3 Decay Time describe decay time can be varied in the range from 0.05s to 22.4s.

Is that meaning I don’t refer to description in 7.3.3.2? And just refer to register description?

Thanks,Ian.

    Hi, Ian,

    The decay time can be effectively programmed with two ways, one is using the values from Register 26, and there is an advanced version where the range is extended as indicated in section 7.3.3.2.2.3. For this, you need to configure Register 104, there is a typo on that section pointing to a reserved register.

    Dear Diego,

     The location of beep generator as below, right?

    we found the abnormal signal when we play 1KHz by beep(On customer unit).

    However, when we play 1KHz.wav, the signal is normal.(On customer unit)

    We guess that issue from the beep generator…, do you have idea about it?

    Thanks, Ian.

    Hi, Ian,

    It seems this question is not related to the AIC3109-Q1; this device does not have a beep generator and the GUI showed is for a different part (AIC31xx?). Can you please clarify and make a new thread if necessary?
