But if he needs 100dBc at 10Hz that is Wenzel's stronghold

I suppose that one of the alternatives that you've explored are the
ABLNO from Abracon http://www.abracon.com/Precisiontiming/ABLNO.pdf
looks just like this one from Crystek:

but that fails the specs, also. If you have a good quality 5 or 10 MHz
source in your
system, you can lock the VCXO to it and clean it up close to the carrier.
Last week, I asked for the prices of the 100 MHz Pascalls (not SMD but
SMA)
but at > € 4K +VAT a piece I better make someone select crystals
myself. :-(
Maybe Axtal has something.
They say that they are 3rd overtone, but it seems more an AT-cut than
a SC, and anyway is around 10dB poorer
SC requires high temperature, that does not go together well with SMD
and low power.
