TLV320AIC3007 Configuration Tool download link nowhere to be found

Other Parts Discussed in Thread: TLV320AIC3007

Hello,


I need to develop a driver for configuring the TLV320AIC3007 using the Cypress FX3 (ARM based microcontroller with limited RAM).

The device page references the pdf "Getting Started with the TLV320AIC3x Configuration Tool ",

but I can't find where to download the Configuration tool.

It is OK if it the tool is only for Windows XP, I just need something to generate some default settings (lets say 48 KHz sample rate for stereo microphone).

Kind regards,

Stjepan Henc

    Hi, Stjepan,

    We don't have a TLV320AIC3007 configuration tool. But we have some examples to configure the device. Please take a look at this document for details. The codes are in hex format w (write) 30 (I2C address) xx (register) yy (data).

    Hi Luis,


    Thank you for the example. If I understand correctly this example should be the closest to what I need:

    # Differential Input to Digital Output.
    # - LINE1L connected to LADC
    # - LINE1R connected to RADC

    w 30 07 80
    w 30 1F F8

    w 30 13 84
    w 30 0F 00
    w 30 10 00

    I think I also need a way to configure microphone bias.

    The datasheet says Page 0 / Register 25 controls that, so I assume something like this would do the trick:

    w 30 19 40

    On the PCB I will have (it should arrive in a week or two) LINE1LP, LINE1RP and MICBIAS connected, and I need to get I2S output.
    The snapshot bellow shows the schematic:

    Hi, Stepan,

    Your schematic is in order. I didn't find any change to do.

    Also, regarding the MICBIAS configuration, you're right. This is enabled with the Page 0 / Register 25. You should remember that this configuration is for differential input. If you're looking for single-ended configuration, you should modify registers related with LINE1L/R routing.

    Best regards,

    Hi Luis,

    Ok, yes it is a single-ended configuration.

    Thank you very much,
