Specifications are subject to change without notice.
R, G, and B signals are inputted via an external ac coupling capacitor.
Except during dc restore period (back porch clamp).
All outputs measured at a 75
Ratio of chroma amplitude to burst amplitude, difference from ideal.
Difference between ideal color-bar phases and the actual values.
Driving the logic inputs with VOH < 4 V will increase static supply current approximately 150 A per input.
