The oscillator you linked to has a fixed frequency output. You might prefer to get a vcxo that has a DC control voltage input that will slightly change the output frequency so it can be adjusted to be closer to "exact." This appears to be the least expensive one with a 10MHz output: https://www.digikey.com/en/products/detail/suntsu-electronics-inc/SVC75C3C07D2-10-000M/12341839
