It changes the cutoff frequency of the RC filter which can in turn affect
DC wander depending on the contents of the signal's frequency spectrum and
io topology. Also changes intialization time from turn-on to steady state.

Hi
I have a question on Decoupling Caps on high-speed differential signals.

Generally it is 0.1uF cap which we place or recommend but if we increase or
decrease the cap value what would be the effect?

Thanks
Srikanth
