Notes:
1. Measured at (VIH(nom) - VIL(nom))/2 and is the absolute value of the worst case deviation.
2. Measured at crossing points for differential clock input or at VTH for single-ended clock input
3. If input modulation is used. Input modulation is not necessary.
4. The amount of allowed spreading for non-triangular modulation is determined
5. Capacitance measured at f = 1 MHz, DC bias = 0.9V, VAC <100mV.
