External Clock/Osillator Current Draw

I was looking for a low power external clock or oscillator but not that familiar with them so I don’t even know a “good” part to read the datasheet. Can anyone recommend one? I know not every clock will work as it depends on the system requirements but just curious wanted to get a general idea from the datasheet of how much current something like that uses. From what I read, I could use an external clock or oscillator...Do people usually go one way or the other? Thanks!


System is an ATtiny45 and 328P processor to wake up every once and a while and check the time, light up a light, etc, but really just looking to get an idea of what to expect for current draw.
