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.

SC requires high temperature, that does not go together well with SMD 
and low power.
