Since a video driver output becomes high impedance at the time of standby, even if it shares a video

output terminal with an input terminal, operation of an input terminal is not influenced.

SAG correction

In order to make the SAG of the video signal as small as possible, we recommend the values of the application

circuit diagram for output coupling capacitor capacitance.

If reducing capacitance due to the demands of miniaturization or the like, check the SAG characteristic for an

alternating black and white bounce signal *1, H-bar signal *2, or other signal for which a SAG effect readily

occurs and use a capacitance that satisfies the demands of the set being used.

As a reference, try the combinations shown below when reducing capacitance. As the capacitance of the

VOUT capacitor is made smaller, SAG becomes greater.
