How to use 4 pin crystal with power?
I have quartz KXO-V97T 8MHz. It looks like it's unusual quartz.

It's only unusual if you consider it to be a quartz crystal: -

It's an oscillator module that contains a quartz crystal and an oscillator circuit hence it needs a power supply.
If you look at the picture you will see that it is to be used on a 2.6 volt DC supply +/- 10%.
