1 These maximum/minimum specifications are guaranteed by characterization over the 4.75 V to 5.25 V range.
2 Note that the ADV7123 exhibits high performance when operating with an internal voltage reference, VREF.
3 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.
3.3 V DYNAMIC SPECIFICATIONS
VAA = 3.0 V to 3.6 V1, VREF = 1.235 V, RSET = 680 Ω, CL = 10 pF. All specifications are TA = 25°C, unless otherwise noted, TJ MAX = 110°C.
