In principle, yes. However not directly clocked by the rubidium itself but
from a clean ttl signal that has been made out of the LPRO's sine. There has
been a long discussion here about the "howto" of this. As a good starting
point I suggest this:

While the ADCMP600 are available well in Germany (for example from FARNELL)
the MSOP enclosure is very tricky to solder and for a bit less in frequency
performance a LT1016 will do it for you too.
Best regards
