Figure 35. Sync Stripper  
The video signal plus sync is applied to the noninverting input  
with the proper termination. The amplifier gain is set equal to 2  
via the two 1 kΩ resistors in the feedback circuit. A bias voltage  
must be applied to R1 for the input signal to have the sync  
pulses stripped at the proper level.  
The blanking level of the input video pulse is the desired place  
to remove the sync information. The amplifier multiplies this  
level by 2. This level must be at ground at the output in order  
for the sync stripping action to take place. Because the gain of  
the amplifier from the input of R1 to the output is −1, a voltage  
equal to 2 × VBLANK must be applied to make the blanking level  
come out at ground.

SYNC STRIPPER  
Synchronizing pulses are sometimes carried on video signals so  
as not to require a separate channel to carry the synchronizing  
information. However, for some functions, such as A/D  
conversion, it is not desirable to have the sync pulses on the  
video signal. These pulses reduce the dynamic range of the  
video signal and do not provide any useful information for such  
a function.  
SINGLE-SUPPLY COMPOSITE VIDEO LINE DRIVER  
Many composite video signals have their blanking level at  
ground and have video information that is both positive and  
negative. Such signals require dual-supply amplifiers to pass  
them. However, by ac level-shifting, a single-supply amplifier  
can be used to pass these signals. The following complications  
may arise from such techniques.  
A sync stripper removes the synchronizing pulses from a video  
signal while passing all the useful video information. Figure 35  
shows a practical single-supply circuit that uses only a single  
AD8091. It is capable of directly driving a reverse terminated  
video line.  
Signals of bounded peak-to-peak amplitude that vary in duty  
cycle require larger dynamic swing capacity than their  
(bounded) peak-to-peak amplitude after they are ac-coupled.  
As a worst case, the dynamic signal swing approaches twice the  
peak-to-peak value. One of two conditions that define the  
maximum dynamic swing requirements is a signal that is  
mostly low but goes high with a duty cycle that is a small  
fraction of a percent. The opposite condition defines the second  
condition.  
The worst case of composite video is not quite this demanding.  
One bounding condition is a signal that is mostly black for an  
entire frame but has a white (full amplitude) minimum width  
spike at least once in a frame.
