[1] C_PD is used to determine the dynamic power dissipation (P_D in µW).
P_D = C_PD × V_CC2 × f_i × N + ∑(C_L × V_CC2 × f_o) where:
f_i = input frequency in MHz;
f_o = output frequency in MHz;
C_L = output load capacitance in pF;
V_CC = supply voltage in V;
N = number of inputs switching;
∑(C_L × V_CC2 × f_o) = sum of outputs.
