Actually I got a problem in designing a good sine wave generator!
I got the folllowing needs:
I does the first step by using the AD7008 but this solution got some disadvantages!
First the 3 chanels are only syncronized by the same resonator.
2nd I can only use a 50MHz resonator, so I got a too many noise voltage on the generated sine wave (only 12 samples ca be take from the LUT)
and third I need a resolution of 14bit by the Output DAC to fine setup a amplitude!
So I thinked about to using an other part with a 200MHz resonator and modulate the amplitude of the sine with an DAC on the reference in!
What did you think is there a easier or better solution for my problem, I didn't thinked about?
Thanks for your help.

I got the folllowing needs:
- 3 syncronized outputs!
Output-Frequency 1 - 10 MHz
changeabe in amplitude and phase
low noise outputs
