These maximum/minimum specifications are guaranteed by characterization over the 4.75 V to 5.25 V range.
Note that the ADV7123 exhibits high performance when operating with an internal voltage reference, V
REF
.

DAC-to-DAC crosstalk is measured by holding one DAC high while the other two are making low-to-high and high-to-low transitions.
4
Clock and data feedthrough is a function of the amount of overshoot and undershoot on the digital inputs. Glitch impulse includes clock and data feedthrough.
5
TTL input values are 0 V to 3 V, with input rise/fall times of −3 ns, measured from the 10% and 90% points. Timing reference points are 50% for inputs and outputs.
