1 Aperture uncertainty includes contribution of the AD9433, crystal clock reference, and encode drive circuit.
2 tV and tPD are measured from the transition points of the ENCODE input to the 50%/50% levels of the digital output swing. The digital output load during testing is not
to exceed an ac load of 10 pF or a dc current of 50 μA. Rise and fall times are measured from 10% to 90%.
