NOTES

1

± 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.
