PCM1754: Clock Error Detection

Akio Ito

Part Number: PCM1754

Hi,

Please teach me the detail of PCM1754 clock error detection. If a clock error is detected, is the output muted or powered down?

Best regards,

Hi, Ito-san,

This device does not have a clock error detection feature, when a clock frame is missing, the outputs will go to a Hi-z/floating state and audio artifacts are likely to occur. For more information about the behavior of the PCM1754 when this issue occurs, please refer to the following wiki:
