PCM2903: Crosstalk issue

Part Number: PCM2903


I'm using this part for Full duplex headset communication. Is anyone having a crosstalk problem where you hear yourself echo when speaking through the microphone? If yes, is there a solution to this issue?

Thank you.


  • Hi Niko,

    Are you referring to the sidetone feature where you can monitor the audio captured by the mic in the headset? There is a slight delay between speech and the sidetone signal, but if you are hearing a longer duration echo this may be another issue.
