Notes
1. H = HIGH state (the more positive voltage)
2. L = LOW state (the less positive voltage)
3. X = state is immaterial
4.
= positive-going transition
5.
= negative-going transition
6. Z = high impedance off state
7. nc = no change
8. O’6 = the information in the seventh shift register stage

MSI
At the positive clock edge the information in the 7th register stage is transferred to the 8th register stage and the
Os output.

9700 fi + ∑ (foCL) × VDD2
15
26 000 fi + ∑ (foCL) × VDD2
where
fi = input freq. (MHz)
fo = output freq. (MHz)
CL = load capacitance (pF)
∑ (foCL) = sum of outputs
VDD = supply voltage (V)
