Part Number: PCM9211
Hi Team,
I have a phenomenon need double check with you. From my customer's feedback, they use PCM9211 in audio speakers and the input is coaxial input, they follow the circuit guide in datasheet. When testing coaxial performance, they have found that coaxial signal can be affected by ground easily. They use external metal connect the ground, it will exist the noise in coaxial signal waveform. This phenomenon exists several projects. Is this phenomenon normal?
The blow picture is the waveform of coaxial noise signal.
Best Regards,
Gust
