This is awful:
It's still Rev 0, from 2003.
The only associated appnote is from 1989!

It may be awe-inspiring to find that Analog Devices got it all exactly right, first time around, but you seem to be saying that they ought to have changed it just because it's old.
You and I get worse as we get older, but integrated circuits stay exactly the same. If it ain't broke, don't fix it.

And specifically what is wrong?
On a sunny day (Sun, 16 Nov 2014 17:29:05 -0800) it happened John Larkin wrote in :
Yes, I recently (or not so recently) had very bad plans for the AD datasheet writer... Probably good enough for a war ciminal trial. :-)
After reading their datasheet about 10 or more times, and trying their example that made no sense to me, but thinking 'I must be missing sometthing so let me try this, but it makes no sense whatsover' I dumped their idea and did it my way. My way works better, is simpler too.
Then the next chip, that fractional 2.4 GHz divider / oscillator where their PLL design software did not run... in Linux wine. Probably the same app writer :-)
Maybe I will still try that chip, ADF4360-1.pdf, anybody used it? Any good?
What's to understand? Looks to be simply a modernized version of my

Gosh, did you invent the comparator?

I love to cook with wine. Sometimes I even put it in the food.
