Dear Team,

For near-end crosstalk, we know that inductive and capacitive coupled current going in the same direction.

But after some length, the near-end crosstalk amplitude becomes constant(Crosstalk saturation).

May I know how it is happening?

I am referring to a microstrip PCB transmission line.

I simulated using Hyperlynx .I keep on increasing the trace length .

After some time what I observed is near end crosstalk amplitude is constant.

It is not varying with trace length.
