We have some questions about AN-0971/AN-1109 APPLICATION NOTE.
There is the following description at Page3.
(1)AN-0971 When the edges mismatch by <20h, where h is the plane to plane pacing, the fields couple out of the PCB very efficiently,
resulting in very high emissions.
(2)AN-1109 When the edges mismatch by 20h where h is the plane-to-plane pacing, the fields efficiently couple out of the PCB,
resulting in high emissions
Q1.AN-0971 -> <20h, AN-1109 -> 20h.
Which is correct description?.
Q2:There are two limiting conditions,Fig2 and Fig3.
Does this section explain which is better between edges are line up or one edges is pulled back?.
If so,which recommendation do you have?.
Pls give the advice to us.
