6. CPD, measured per flip-flop, is used to determine the dynamic power consumption.
PD (per package) = VCC ICC + Σ(VCC2 fI CPD + VO2 fO CL + VCC ∆ICC D) where:
VCC = supply voltage
∆ICC = flow through current x unit load
CL = output load capacitance

NOTES:
9. VOLP is measured with respect to a ground reference near the output under test. VOHV is measured with respect to VOH.
10. Input pulses have the following characteristics:
PRR ≤ 1MHz, tr = 2.5ns, tf = 2.5ns, skew 1ns.
11. R.F. fixture with 700MHz design rules required. IC should be soldered into test board and bypassed with 0.1µF capacitor. Scope and
probes require 700MHz bandwidth.
