NOTES
1VAA = 5 V ± 5%
2Temperature range (TMIN to TMAX); 0°C to +70°C; TJ (Silicon Junction Temperature) ≤ 100°C.
3Pixel Port is continuously clocked with data corresponding to a linear ramp.
4Clock and data feedthrough is a function of the amount of overshoot and undershoot on the digital inputs. Glitch impulse includes clock and data feedthrough.
5TTL input values are 0 to 3 volts, with input rise/fall times ≤ 3 ns, measured at the 10% and 90% points. Timing reference points at 50% for inputs and outputs.
6DAC to DAC Crosstalk is measured by holding one DAC high while the other two are making low to high and high to low transitions.
Specifications subject to change without notice.
