Crystal and ntsc
Hello,
I would like to know how sensitive the NTSC chromaburst frequency is to the Propeller crystal frequency? Can I use an 80MHz oscillator and still have the TV functions work? Are there certain frequencies that are recommended or that should be avoided?

That the clock input was varied over that range.
Impressive design of that silicon to be so adaptable.
Chip, and Company, did a highly impressive design for us to play with. Congratulations, guy!

Wow, thanks for trying that out. I'll have to analyze more for myself how the color can still work with all kinds of clock inputs. I was expecting jitter problems and color to not work properly for various clocks.
