TAS5411-Q1: Questions of TAS5411-Q1

Jimmy Lai
Expert 6845 points
Part Number: TAS5411-Q1
Other Parts Discussed in Thread: TLV320AIC3104-Q1, TAS5431-Q1, TPD3S714-Q1

Dear Team,

Could you help to check does TAS5411-Q1 can meet spec as below?

Speaker interface: The emergency call module requires a built-in audio amplifier circuit to drive (power supply: 4W, 4Ω) a dedicated speaker for the emergency call system. When an E-call occurs, the emergency call module directly drives the dedicated speaker to sound; the emergency call module is for a dedicated speaker The speaker has self-diagnosis function; -->It's ok. Choose TAS5411-Q1
Dual microphone interface
1. MIC IN: The emergency call module can support 1 MIC IN power supply (whoever uses it supplies power), supports 1 MIC IN signal input, and under certain circumstances, can BY BASS two MIC signals to the HU; emergency call module Powers 1 microphone (8V, 10mA)); the emergency call module provides self-diagnosis function for the microphone;
2. MIC OUT: HU provides 1 MIC IN interface to the emergency call module. When the MIC is connected to the emergency call module, the emergency call module sends the signal BY PASS to the HU; the emergency call module provides diagnostic methods for HU and emergency calls. Whether the MIC connection between modules is normal;

1. Is the MIC IN connected to the TLV320AIC3104-Q1 and able to supply the MIC Bias (8V, 10mA) sufficient? And can it detect whether the MIC is normal (Open, short GND or power)?
2. Can the MIC IN be connected to the TLV320AIC3104-Q1 and be able to BYPASS the MIC IN to the MIC OUT to the host MIC? Or do I need to plug in an external audio analog switch (SPDT Analog Switches)? If an external plug-in is needed, please suggest the vehicle specification number.
3. Does the LINE OUT output have a self-test function?

Many Thanks,

Jimmy

    Jimmy,

    Use the TAS5431-Q1 instead as it is a newer device with the same performance as the TAS5411-Q1.  This device will work perfect for your E-Call.  

    I will let the codec team respond on the TLV320 questions.

    Regards,
    Gregg Scott

    Hi Jimmy,

    1. No, the MICBIAS supports only up to 3.6V and it does not support input diagnostic. See page 7 of the datasheet.
    2. Here is a block diagram of this AIC3104 device where MIC1L/R can connect directly (bypass) to LO.

            3. No, it doesn't.

    Here is a link to an e-call reference design TIDA-00724 reference design | TI.com.

    Regards.

    Hi pdjuandi.

    Below is AUDIO function block diagram.

    According to your reply e-mail, you answered me about MIC IN bypass to MIC OUT through TLV320AIC3104-Q1.

    Could you please describe you don't understand what?

     

    There are something about the E-CALL system discussed with you.

    1. How design self-test in the E-call system? Such as SOS Button, MIC, AIR bag signal….
    2. Is the TAS5431-Q1 MP?
    3. Our end customer demand for MIC  Bias is 8V, 10mA.

      So, how can we design MIC path connect to TLV320AIC3104-Q1’s pin? Have something is important?

    4. Is TLV320AIC3104-Q1 have echo Cancellation function?

    The E-CALL require USB2.0 protect function.

    Could you help check TPD3S714-Q1 is advice?

    Thanks a lot.

    Jimmy

    Jimmy,

    What do you mean by question 2?  I do not know what you mean by "MP".

    Hi Jimmy,

    1. End system testing is not our expertise, we are not familiar with building such self-test.
    2. Do you mean device is in production?
    3. Your MIC input needs AC-coupled since AIC3104-Q1 MICBIAS does not support voltage higher than 3.6V. We have new device with MICBIAS up to 10V in TAC5412. When is the customer timeline? 
    4. No, it does not support AEC.
    5. You can check with TPD3S714-Q1 team.

    Regards.
