NOTES

± 5% for all versions.
2Temperature range (T
MIN 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. T
J = 100°C.
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 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.
