Part Number: PCM1754

Hi Team,
Customer uses PCM1754 and cusotmer found the issues while using I2S switch to switch the two audio source.
While switching, the PCM1754 has abnormal output.

Could you please recommend the latest solution that the output can be auto mute if the clock not right or changing?


BR,

    Hi Scott,

    I do not think any of our DACs have an auto-mute functionality if the sources is invalid. Generally I recommend that the use assert the MUTE before the change occurs or force the DIN line to be code zero until the new clocks are established.

    Thanks,
    Paul
