A sensor I am using needs a 25Mhz clock signal for it to operate. I was wondering if it is possible to generate such a high frequency with an arduino nano opposed to creating it with bare components.
If not possible with arduino, is there another way to do this easier than creating a circuit for the clock signal?
I doubt it. Since a Nano runs at 16 MHz, I don't see a way to make it generate the clock signal you're looking for.
Some of the Teensy range run a lot faster and could probably do it, but it would likely be a lot cheaper to build a custom circuit.
I'd go with an oscillator, here are thru hole examples. Apply power & Gnd, get 25 MHz out.

This is interesting actually because I am planning on using a black pill which runs on 96Mhz so might it be possible with a 96Mhz board?

The 'tutorial' from which I got this uses this setup. What is the difference between just an oscillator and a circuit around it? What do I need?
Thanks for helping me out.
Edit: forgot image.
You may be able to generate a 25 MHz clock signal with the black pill. That will require extensive study of the processor data sheet. Much easier to follow the tutorial and use a canned oscillator.
This question makes no sense at all. Please try again.

Bottom left diagram shows a 25Mhz crystal with other components such as 2 inverters and a resistor. Why would you use this setup instead of just using a 25Khz crystal as described by @CrossRoads
The oscillator in a can (described by Crossroads) contains the crystal, capacitors and inverter components pictured on the bottom left.
Your choice which to use.
Aha, that'll be my question solved then!
Thanks
