A8091/AD8092
The other extreme is a full white video signal. The blanking
intervals and sync tips of such a signal have negative-going
excursions in compliance with the composite video
specifications. The combination of horizontal and vertical
blanking intervals limit such a signal to being at the highest
(white) level for a maximum of about 75% of the time.

As a result of the duty cycles between the two extremes, a 1 V p-
p composite video signal that is multiplied by a gain of 2
requires about 3.2 V p-p of dynamic voltage swing at the output
for an op amp to pass a composite video signal of arbitrary
varying duty cycle without distortion.
Figure 36. Single-Supply Composite Video Line Driver
The feedback circuit provides unity gain for the dc biasing of
the input and provides a gain of 2 for any signals that are in the
video bandwidth. The output is ac-coupled and terminated to
drive the line.
Some circuits use a sync tip clamp to hold the sync tips at a
relatively constant level to lower the amount of dynamic signal
swing required. However, these circuits can have artifacts like
sync tip compression unless they are driven by a source with a
very low output impedance. The AD8091/AD8092 have
adequate signal swing when running on a single 5 V supply to
handle an ac-coupled composite video signal.
The capacitor values were selected for providing minimum tilt
or field time distortion of the video signal. These values would
be required for video that is considered to be studio or
broadcast quality. However, if a lower consumer grade of video,
sometimes referred to as consumer video, is all that is desired,
the values and the cost of the capacitors can be reduced by as
much as a factor of 5 with minimum visible degradation in the
picture.
The input to the circuit in Figure 36 is a standard composite
(1 V p-p) video signal that has the blanking level at ground. The
input network level shifts the video signal by means of ac
coupling. The noninverting input of the op amp is biased to half
of the supply voltage.
