OPTIONAL OUTPUT FILTER
If an output
fi
lter is required for the CVBS, Y, UV, Chroma and
RGB outputs of the ADV7194, the following

lter in Figure 100
can be used in 2

fi
lter is not required if the outputs of the ADV7194 are con-
nected to most analog monitors or TVs, however, if the output
signals are applied to a system where sampling is used (e.g.,
Digital TVs) then a
fi
lter is required to prevent aliasing.
