CPD x fosc x VCC2 + S (CL x VCC2 x fo) + 2Ct x VCC2 x fosc + 16 x VCC
CPD x fosc x VCC2 + S (CL x VCC2 x fo) + 2Ct x VCC2 x fosc + 460 x VCC
CPD x fosc x VCC2 + S (CL x VCC2 x fo) + 2Ct x VCC2 x fosc + 1000 x VCC
NOTE:
1. Where: fo = output frequency in MHz; fosc = oscillator frequency in MHz;
S (CL xVCC2 xfo) = sum of the outputs; CL = output load capacitance in pF;
Ct = timing capacitance in pF; VCC = supply voltage in V.
