Default Crystal oscillator circuit design

I need to make a fixed frequency oscillator at 4.194304MHz.
I thought that a crystal-based circuit would be best and have chosen this crystal as it's ubiquitous and cheap :https://uk.farnell.com/qantek-techno...9us/dp/2508442
The datasheet states that the maximum drive level is 1.0mW - can anyone tell me what the best circuit to use with this crystal is, that will not overdrive it and also has the best frequency stability with lowest jitter ?
I'd like to know how to calculate the drive power in general as well.

Cheers,
Andy
