Hello

 

My customer query is about AN-1109 Page.8 Figure.10. 

Does ADI have recommendation value for below item?

1.What is the VIA diameter?

   ("test boards used 4 mm via spacing for their evaluation boards."  in the document)

 

2.How wide guard ring trace?

 

<back ground>

The customer is going to PCB re-design for mitigation emission.

They have evaluated ADuM1301 for auxiliary  inverter.

Their EMI target  CISPR25.

 

Best Regards

T.Kamino
