CONFIGURING THE SCALER
The 7812DCDA2Q series products utilize a high performance multi-tap polyphase filter to perform scaling
and aspect ratio conversion on the input video signal. The Scaler control tab is used to define the cut-off
frequencies of these polyphase filters and the aspect ratio conversion that the module will perform. Static
side panel colors and output AFD stamping values are also adjusted within this tab.
