Hello ,

As per my project requirement, i need to design USB OTG which meets the ESD standard IEC 61000-4-2 level 4) and EMI standard CISPR-11.

In ST website i found two categories:

1. Common mode filter with ESD protection

2. EMI filter and ESD protection

Both claims, same ESD protection levels.

So, i am not sure which is used for what and what is the basic difference between them.?

Kindly suggest.

Regards,

Govind.

Hi,

To solve interference problems, you must understand them. So at first please begin by describing the ways

that RF interference is coupled into equipment and detected. There are several principal mechanisms

at work. You should study this tutorial thoroughly to understand how these things work.

Hope it helps,
