And the Loop inductance will be changing. Lowest loop inductance will be
achieved with the highest capacitance value available of the same component
size.

Betreff: [SI-LIST] Re: AC decoupling caps on Highspeed differential signals
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
