DS90UB935-Q1: EMC RE testing issues

Hi Tommy,

Thanks for reaching out about this issue. Would it be possible for you to provide the layout files in non-PDF form? It is quite difficult to look at the layers together and see what signals are present on them.

Best,

Thomas

Ok, updated the following file.

Please help to check it.

Thanks

Hi Tommy,

Thanks for providing the layout file, this will be helpful. I'll take a look and get back to you by the end of the week with feedback

Best,

Thomas

Ok, I look forward to your reply.

Many Thanks!

Hi Tommy,

One thing that I'd like to check on quickly, do you know what stage this project is in? There are some significant issues with this layout & this application would likely continue to show these problems until the layout is corrected.

One other item of note, have we worked with the power supply team to check if there's any room for improving supply noise?

Best,

Thomas

The project is in the design and testing phase. We can also fix it now.

The power supply has not been checked. We will remind customers to check this part.
