    i have read ad9830 dds ic datasheet, but i have steel problem how i
    should program it, for example i want to use pararel port for
    interfacing , and for example want 3.1MHZ on out put, how i should
    use D0 to D15 and A0,A1,A2? should i use both freq reg ( 0,1) and
    all 4 phase reg ? or one is enouth?
    any help would be most appreciated

  2. What frequency is your clock ? You need a clock that is faster than
    twice your output frequency, though a bit more is recommended.
    10MHz ? 20MHz? 50MHz?

    I've got some code on my web site for the AD9850 that should help.

    Interesting, I'm just starting my work on 2104. Just got the proto board from Nohau.
    I saved the link for the first chance I get to work on it.
