PCM1754: abnormal sound at the beginning and the end of each data transmission

Vito Liao

Part Number: PCM1754

Hi Sir,

Our customer has an issue about PCM1754DBGR. They found that they can hear abnormal voice "PO" at the beginning and the end of each data transmission. They tried to enable the mute function but the abnormal voice "PO" is still present.

Thanks!
