Perhaps too much uncertainty or unwanted placement in the edge crossover
detection points, eating away timing margin in the worst-case timing
analysis and increasing skew relative to other signals.
If all receivers behaved identically and there is no noise in the system,
then the effect may just be a change of duty cycle. But this isn't likely
and so, I would think, signals approaching sine waves should be avoided.
