Note 1: See Dynamic Test Circuits section.
Note 2: 3dB typical crosstalk improvement when R
S
= 0.
Note 3: Input test signal: 3.58MHz sine wave of amplitude 40IRE superimposed on a linear ramp (0 to 100IRE). IRE is a unit of
video-signal amplitude developed by the International Radio Engineers. 140IRE = 1.0V.
Note 4: Guaranteed by design.
