Near end Crosstalk Saturation-Physics Behind it

HARI T O1

Dear Team,

This is a general question.

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

But after some time change in trace length, does not change the near-end crosstalk amplitude. It becomes constant(Crosstalk saturation).

May I know how it is happening?

Hello HARI,

Please provide more information. Crosstalk applies to a number of device types and family of devices. What type of application are you referring to here?

Thanks,

Hi Lenord,

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.

Hari,

While crosstalk does affect devices in our portfolio, I think this may be better suited for the high-speed interface team. I'm reassigning this thread to that team.
