APPENDIX 6
OPTIONAL OUTPUT FILTER
If an output 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
× Oversampling Mode. In 4× Oversampling
Mode the lter in Figure 102 is recommended. The plot of the
lter characteristics are shown in Figures 101 and 103. An output

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 lter is required to prevent aliasing.
