PCM1753: Power-on reset timing

Sadanori Kato

Part Number: PCM1753

Hi,

The power-on reset timing is mentioned in PCM1753 data sheet as follows.
For example, please let me know if you have any advice regarding pop noise such that it is better to apply SCLK to PCM1753 after the power supply has stabilized.

Best regards,
Kato

Hi Kato-san,

Basically, there is a risk of a pop noise from the device whenever there is a clock error, as well as when the delta-sigma modulator activates. That can occur at startup and is difficult to avoid without an external mute circuit. In general, I recommend that you apply SCK before power-up.

Thanks,

Paul
