ADuM6402 Question

Hello Thank you for your support always.

 

Our customer who is considering ADuM6402 has question about AN-0971.

 

There is a comment as below.

The rectifier circuit on the secondary side effectively doubles this frequency during the rectification process.

 

What is this meaning?

 

The customer has 360MHz EMI noise issue. They could clear 180MHz with shielding and something.

But it would be difficult to improve 360MHz EMI noise.

 

I recommend edge guard and so on.

 

Regards,
