Clock and data feedthrough is a function of the amount of overshoot and undershoot on the digital inputs. For this test, the digital inputs have a 1 k
resistor to
ground and are driven by 74HC logic. Glitch impulse includes clock and data feedthrough, –3 dB test bandwidth = 2

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.
