May I ask what you want to achieve? Resp. what you need a 10MHz reference for?

In general I would agree with Bill Houlne's comment that it's probably
easier to use a different reference that already has a 10MHz output.
Also keep in mind, that an output that has been designed as an PPS output
might not work as well as an output for 10MHz.

I am not master of desaster on this list, but it's usually ok to offer
this kind of stuff, as long as it is time-nut related.

Gruess und guets neus!
