Capability of AD9850 and AD9851

I need a signal generator good up to 60MHz and I saw that the AD985x chips can be bought on eBay cheaply, but I can't find any conclusive data on the fastest signal they can produce.

Is anyone using an AD9850 to produce a sine wave at or over 60MHz? Or do I need to get an AD9851?

I might be way off base but I think you're barking up the wrong tree. Let's wait and see if anyone can answer your question.

From the research I've done on the AD9850, the signal starts to degradate after 40MHz; as well as attenuate. Better to go with the AD9851.
