REV. B
If an output filter is required for the CVBS, Y, UV, Chroma and RGB outputs of the ADV7175A/ADV7176A, the following filter in
Figure 67 can be used. Plots of the filter characteristics are shown in Figures 68, 69 and 70. An output filter is not required if the
outputs of the ADV7175A/ADV7176A are connected to an analog monitor or an analog T V; however, if the output signals are ap-
plied to a system where sampling is used (e.g., digital T V), a filter is required to prevent aliasing.
