ADV7181C - NTSC Square Pixel Output

Hi Ed,

I was taking for granted that you have to change the pixel clock.  You cannot get square pixels without the 25.5454Mhz clock.

The line on page 26 about YPbPr without a modulated color component is referring to component video. Given that they tell you not to do it anyway since there is a mode for that, I'm not sure why they even mention it. It has nothing to do with NTSC square pixel mode.
