I guess since my initial prototype circuit just has a few parts, the most complex being the 20 lead AD9834, my gut feeling was that a part with 48 leads must have a lot of stuff I don't need, and I wanted to keep it simple. Do you have any clock generators with 16 leads? I looked at the AD9518 manual, there's a lot to it, would prefer not to get bogged down with this much complexity, if possible.
My current needs are these:
1) experiment and learn about the clock generators. That knowledge will be needed for implementing the ADC portion later.
2) need a clock now for the AD9834 circuit, and want to test several clock frequencies.
