Differential signals use two lines instead of one. This means twice the switching activity compared with use of single ended transmission. How then does use of differential signalling achieve lower power in FPGAs since power dissipation mainly occurs when output is switching state?
Also, do FPGAs have real differential buffers inside or always use "emulated differential signals"?
Finally, shouldn't the use of termination resistors always lead to higher power dissipation relative to single ended signals for the same application since the termination resistors will always be sinking current to the ground?
