I am using the part ADA4412-3ARQZ (Triple Video Filter) in my project. Please tell me the cut-off frequency details for the composite video,s-video and RGB Video so that I can set the Filter Cut-off selection.
Did you refer the data sheet at http://www.analog.com/media/en/technical-documentation/data-sheets/ADA4412-3.pdf ?
Yes.I have gone through the Datasheet.But the details are not sufficient.
I need the exact Bandwidth details of the Component,RGB and composite Video , so that i can set the desired cut-off frequency for each in the filter IC.
I am checking with part specialist on this one.
Cutoff frequency is dependent on the format timing. For NTSC (SD) you should use the 9MHz filter settings. For 480p (ED) you should use the 18MHz settings while for 720p (HD) you should use the 36MHz settings
I am not sure if this is the answer you are looking for.
I have three different video signals(Composite,s-video and Component video) to filter. The mentioned fiter IC part in this discussion has three inputs. I am not sure whether i can go with a Single IC to set a common cut-off frequency for the three different video inputs or depending upon the bandwidth,do i have to use a separte filter IC for each video type so that i can set a separate cut-off frequency for each input.
Please suggest a possible one.
Thank you. Awaiting a reply from you.
You can put all 3 signals through the part and then select the appropriate filter depending on the format via the sutoff select pins and simple processor control.
