Video with RCFAST?

CassLan

Hi all,

This may seem like a dumb question, is it possible (or does it exist) to have an NTSC video output without using a crystal, like using RCFAST?

Rick -- no, the timing isn't accurate enough. The RC clocks can vary widely in frequency depending on manufacturing tolerances, temperature, supply voltage, and so on. Video requires an accurate clock so the monitor can sync.

Thats what I figured, thanks!
