I cannot get a color output from the device. We are only using DAC-A to provide an NTSC output. I've tried all the register settings and nothing seems to give any chroma output. Can you recommend settings? I am using slave mode 2 for timing.
1) First of all this device is not recommended for a new design.
2) Has it ever output color if this in older design?
3) What's your input format, 656 or 601?
4) Do you see the color burst on the output?
5) Is the clock input correct? 27MHz?
The recommended setting are those shown in the datasheet Appendix 9
