I bought a OSC5A2B02 that is a cheap 10MHz oven controlled frequency generator. What can we do with that?

Presentation

Principle

An oven controlled frequency generator that spits a very clean 10MHz. 5v in, takes 600mA at startup to warm and 200mA after that to maintain. Praised vastly on the net for the excellent cost/performance when a precise 10MHz is needed.
