APPENDIX 7—OPTIONAL OUTPUT FILTER
If an output filter is required for the CVBS, Y, UV, chroma, and
RGB outputs of the ADV7174/ADV7179, the filter shown in
Figure 79 can be used. Plots of the filter characteristics are
shown in Figure 80. An output filter is not required if the
outputs of the ADV7174/ADV7179 are connected to most
analog monitors or analog TVs. However, if the output signals
are applied to a system where sampling is used (e.g., digital
TVs), then a filter is required to prevent aliasing.
