Notes

1. CPD is used to determine the dynamic power dissipation (PD in µW).

PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in Volts;

∑ (CL × VCC2 × fo) = sum of outputs.

2. The condition is VI = GND to VCC.
