I read in all of these datasheets that the AD723,AD725, and AD725 all require interlaced inputs. If I want to feed a  pc's vga output into one of these IC's, would these still convert the RGB to composite? Are there other solutions from Analog Devices that are RGB-to-NTSC Encoders that do not require an interlaced input? The AD723,AD725, and AD725 all looked like good solutions because they can be hardware configured and do not require some configuration scripts over I2C.

 
Any help on this would be great.

 
Thank you,

 
Scott

    Hi Dave,
    
 
    My goal is to have this go onto a PCIE bus. I am currently using another part that has NTSC input and PCIE output and I was going to try and convert the XGA to NTSC so I could add it as another input. My end goal is to get the XGA to a PCIE bus but I did not find any IC combinations/solutions that would be able to make that conversion.
    
 
    Does Analog Devices have any time of chipset solution that can do this kind of conversion without losing resolution?
    
 
    Thanks,
    
 
    Scott
