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. FILTER I/P 75Ω 270pF 22pF 1.8μH 330pF Figure 79.
