Sapieha and Others,

Will you please summarize the success and failures of various crystal/clock combinations?
What is your take/opinion on a PLL approach like EconoOscillator (DS1077)?

    Mike,

    You won't be able to generate video (at least not color video) if the DS1077 is the system time base. Its +/- 0.5% frequency tolerance (initial and over temp) is too loose.

    There is a DDS (direct digital frequency synthesis) chip that I've heard of in a few places, that is good for
    radio signals up to at least 30MHz, but I don't recall the number or manufacturer. It probably has stability
    more like a crystal than other common options, except that it is variable frequency.
