desaster blogged about his VGA framegrabber project:
The project got a nice boost when I found TVP7002 on TI’s site. It’s a video digitizing chip, featuring 3x ADC (one for each color channel) and a PLL system for generating the pixel clock from the HSYNC input. Compared to alternatives, this seemed to be quite nicely priced, and well available. In fact, TI was kind enough to provide me with free samples!
