Part Number: TLV320AIC3254

Hi Ti team,

    We found that the distortion of TLV320AIC3254 was too large, up to 2%. The 1KHz signal was played, and the measured waveform was shown in the figure below. We have broken all the periphery of the analog output and eliminate PCB interference as far as possible. sch as attachment

Could you give us some advise for this?thanks !

  • Hi, Jimmy,

    Can you please share the register configuration of the device? Also, can you please share the frequency of the clocks provided to the device, as well as the sampling rate?

    Is the issue shown on the line or headphone outputs?

    Best Regards,

    Jimmy,

    Can you set the Codec to I2S master? Using a non-synchronous MCLK is not supported in slave mode.

    best regards,
