APPENDIX 6
OPTIONAL OUTPUT FILTER
If an output
fi
lter is required for the CVBS, YUV, Chroma, and
RGB outputs of the ADV7190/ADV7191, the
fi
lter in Figure
94 can be used in 2
×
Oversampling Mode. Figure 96 shows a
filter that can be used in 4
×
Oversampling Mode. The plot of
the
fi
lter characteristics are shown in Figures 95 and 97. An output
fi
lter is not required if the outputs of the ADV7190/ADV7191
are connected to most analog monitors, or TVs; however, if
the output signals are applied to a system where sampling is
used (e.g., Digital TVs), a
fi
lter is required to prevent aliasing.
