 07 May 2008 10:47 falling and rising edge pulse: is it high speed design? |
|

SI/ High Speed Design Sifus,Mahagurus,
I am quite new to high speed design. I am currently designing an evaluation board to charecterize my IC.
I need to input a rising edge and falling edge signal with rise time lesser than 0.1ns to my ic.
My question: Will the PCB trace being used be a high speed trace?
I can input a pulse with any frequency. I need a pulse with minimum propagation delay.
Thanks

yes.
you have to use rising timg to check if you have to put termination resistors into you PCB trace.

you have mentioned to use termination resistors? is it also the case for just a rising edge pulse?
i am not using a square/sinusoidal wave signal with fixed frequency.
