Oh..right. Didn't think about this (although i just read it in Vigs tutorial).
While we are at it. Is there any good resource (book, webpage, papers)
on the different crystal oscillator circuits and their advantages and
disadvantages? I couldn't find anything usefull but a few general circuits
(mostly from RF and ham radio books).

Could you explain a little bit more about ADEV vs phase noise?
The trouble with you, Shev, is you don't say anything until you've saved
up a whole truckload of damned heavy brick arguments and then you dump
them all out and never look at the bleeding body mangled beneath the heap
