Hi,

This subject is my mistake!

Dirrential probe contact error!

Sorry! K**bleep**ij Goel

But ,

We have another problem!
It comes out low voltage at 101010 data at 5GHz. (This voltage Swing 30)

The next one, 11001100, comes out right.
As shown in the picture below.


But at 2GHz, it comes out normally.
Why does it only come out like this at high frequencies?

Thanks!
