The max/min specifications are guaranteed over this range. The max/min values are typical over 3.0 V to 3.6 V range.
Ambient temperature range T
TTL input values are 0 V to 3 V, with input rise/fall times ≤3 ns, measured between the 10% and 90% points. Timing reference points at 50% for inputs and outputs.
Analog output load ≤10 pF.
Guaranteed by characterization
Output delay measured from the 50% point of the rising edge of CLOCK to the 50% point of full-scale transition
Pixel Port consists of the following:
