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.
