1. Skew control range is a function of VCO frequency (fVCO). In ne skew mode TSKRANGE = 7/(16 x fVCO).
In coarse skew mode TSKRANGE = 7/(8 x fVCO).
2. Skew step size is a function of VCO frequency (fVCO). In ne skew mode TSKSTEP = 1/(16 x fVCO).
In coarse skew mode TSKSTEP = 1/(8 x fVCO).
3. Only applicable to outputs with non-zero skew settings.
