Hi All,

 

The topology is below. And ibis file is very large, I will share with you if
needed after deleting unnecessary information.

Naftali,

 

I am not sure I understand what the “The topology is one on one” is

referring to in the original question. So I am not sure what

you mean by “set a very same length to both T branches” either. Please

clarify your question.

 

Thanks,

 

Arpad

Do you mean that If he will set a very same length to both T branches –
then the phenomenon will disappear?

Grace,

 

It looks like that the first ledge is the voltage that the

driver can drive with the load imposed on it by the T-line.

Once the reflection comes back to the driver the voltage

steps up to the full swing levels. This is basic T-line

theory.

Hi All,

 

  The topology is one on one. The simulation result is below. I am curious
about the simulation circled

 

by red pink. What’s the cause? Could someone give me any hint?

 

  

 

Thank you.

 

Grace
