Interesting. Maybe not the optimum oscillator for a GPSDO.

There are special "wide-pull-range" VCXO's where a 10MHz unit will indeed
have sensitivity of 600Hz/V or more. e.g.
I don't know exactly what Epson does inside that particular unit, but a
trick to get wide pull range with discrete circuits is to put two or more
crystals in parallel.
