Hello David,

I hope al is great with you.

First, I would like to recommend the following device configuration as a reference for your design.

Could you please confirm that you are using the same configuration?

Please note that the SGTL5000XNAA3 device is obsolete, you may consider it for your further designs.

Hello diazmarin

My sechematic design also used external regulator.

pwr_3v3 also used p# ltm4644 pwr regulator.

VDDIO, VDDA, VDDD power is good.

When the audio jack is connected, the audio codec operates normally.

However, when i unflug the MIC jack and then flug in again under normal conditions, the audio codec does not work from reboot.

if you have the other solution, pls inform again.

Hello David,

Please review my recommendations below:

1. From the supply voltage, could you please make sure that VDDIO/VDDA are supplied before the VDDD? The preferred supply sequencing is VDDIO/VDDA (doesn’t matter which comes first) and then VDDD.
2. Once again, I do recommend using the SGTL5000 Evaluation Platform as a reference for your design. Please find the schematic attached. Is the rest of your design within the recommended configuration?
3. Just as a comment, your C147 is 1uF. We do recommend adding a 0.1uF. Have you tried to replace such capacitor?
4. Do you have the same issue removing the ferrite?

Regards,

David
