Notes
1. H = HIGH state (the more positive voltage)
2. L = LOW state (the less positive voltage)
3. X = state is immaterial
4. tn + 1 = state after next LOW to HIGH transition of CP

1 500 fi + ∑ (foCL) × VDD2
10
6 900 fi + ∑ (foCL) × VDD2
15
18 900 fi + ∑ (foCL) × VDD2
where
fi = input freq. (MHz)
fo = output freq. (MHz)
CL = load cap. (pF)
∑ (foCL) = sum of outputs
VDD = supply voltage (V)
