It takes the video at 1.0V p-p, with a 10K input impedence, and a sync signal, and produces composite output, either PAL or NTSC, depending on the crystal you use, and a strap. The part number is MC1377, and I think that it's only a couple of bucks. The data sheet I have includes the application circuit, as well as one showing an interface to an RF modulator. Sooooo, if you can get it from digital to analog RGB, this will get it to composite. Kevin D. Hunter AT&T Consumer Products Rm 1L-337 Holmdel, NJ 07733
