Quick reference data
[1]
CPD is used to determine the dynamic power dissipation (PD in W).
PD =CPD × VCC2 × fi × N+ ∑(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
∑(C
L × VCC
