VDD Typical formula
Where
PD
dynamic power dissipation 5 V PD = 1100 fi + (fo CL) VDD2 (W) fi = input frequency in MHz;
10 V
15 V
PD = 5000 fi + (fo CL) VDD2 (W)
PD = 14200 fi + (fo CL) VDD2 (W)
fo = output frequency in MHz;
CL = output load capacitance in pF;
(fo CL) = sum of the outputs;
VDD = supply voltage in V.
