LSE crystal selection

Question asked by Argail on Nov 11, 2013
I've read the AN2867, and calculated that for having a gain margin of 5, the recommended crystal should have a max ESR of 50K and 6pF load for a minimal 3uA/V transconductance. This will not allow to use any tiny smd crystal, for example the Microcrystal CM7V-T1A.

Is there any advice about this?
