We are using the ADV7393 connected to a TI DM648 DSP to output NTSC video. When put the part in square pixel mode and output video, we get output video that is squished horizontally by about 14 pixels or a little over 2%. Do you have any information on this? We are following the setup in Table 79 from the data sheet. I have verified my clock at 24.5454 Mhz. I don't see any other parameters that could result in this scaling. Any ideas?
