1. Skew control range is a function of VCO frequency (fVCO). In fine skew mode TSKRANGE = 15/(8 x fVCO).
In coarse skew mode TSKRANGE = 15/(4 x fVCO).
2. Skew step size is a function of VCO frequency (fVCO). In fine skew mode TSKSTEP = 1/(8 x fVCO).
In coarse skew mode TSKSTEP = 1/(4 x fVCO).
3. Only applicable to outputs with non-zero skew settings.
