Hi, TI guys.

I had made a thread to be reviewed for MPU system.
There is the link and explanation of my design in it.

I was requested to make a new thread for feedback of PMIC circuit part.

I have some problem attaching a file to E2E, so please check the schematic file at a reply in my previous thread reviewing MPU.

URL : AM62A7: Urgent request to review MPU circuit

Give me a feedback about my PMIC design.

Regard.

Hello HOGYUN,

I see the link you have provide leads to a discussion where Kallikupa reviews the schematic but the specific link to the schematic I do not see, can you paste the URL to the schematic instead of the E2E link?

BR,

Nicholas

Hi, it's been a while.

This thread was made a week ago.
Do you have any update for the review?

Now I start procedure of sample production.
PCB artwork is almost completed and, bare board will be in production.

I would like you to let me know before the procedure goes too further when I can still modify the schematic.
I wait for any responce.

Regard

Hello Hogyun,

My apologies, your schematic is very well done.

My comments are as follows:

Please try to route this pseudo differential pair all the way to the point of load (load capacitors at SoC side).

Just double checking since I don't see a part number here, did you read the section 9.2.1.2.3 Crystal Oscillator in the datasheet to make sure 9pF load capacitors are appropriate?

Best Regards,

Nicholas McNamara

Hi Nicholas,
Thank you for your feedback.

I have missed load cap value calculation.
Now, I changed it to 6pF cap.

After that, I think my role designing circuit is finally complished.
I hope the sample is made and functional well.

Regard,

Hogyun Ryu

Hello Hogyun,

Thank you for feedback and letting me know the review amounted to any changes, but schematic for the PMIC was very well done, thank you!

Best Regards,

Nicholas McNamara
