> Finally, an off-the-shelf device! But why is it only rated for 25MHz? Because that's more than enough for scanning a screen-width's-worth of samples from the analog CCD snapshot. In a digital camara, the CCD columns basically capture the image instantaneously. It has an infinite sample rate! Then the data is shifted out the CCD some rate that basically doesn't matter, as long as it isn't so slow that it takes seconds.
