We use discrete component adder made a CVBS video processing circuit, is the complete compound blanking and composite sync signal synthesis CVBS signal, but the image has been, and you won't come with MC1377 chip out of the image, but too much interference, is there a more appropriate black-and-white CVBS coding circuit or chip recommended, thank god!

Look at the AD723/AD724/AD725
