Hi,
I have a circuit (see attached) and I am wondering what happens to a differential signal that gets generated in U1 and received by U2.
Lets say the signal has a 400-600mv swing at the output of U1.
Would I see the following at U2? Vout = R2/Rs+R2 * Vin : Vout= 50/10+50 * 600mV = 500mV
OR
Vout = R2/Rs+R2+50 ohms (transmission line): Vout = 50/10+50+50*600mV = 272mV
In other words, do you factor in the 50 ohm trace?
Thanks!
