Pixel Port is continuously clocked with data corresponding to a linear ramp.
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.

T T L input values are 0 to 3 volts, with input rise/fall times
≤
3 ns, measured at the 10% and 90% points. T iming reference points at 50% for inputs and outputs.
6
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.
