What is the difference between Crystal and Resonator?

Aside from the fact that crystal and resonator are sources of the clock, you can still notice a whole lot of differences between crystal and resonator. The first notable difference between the two devices is actually on the accuracy. Crystal is more accurate than resonator because it has a tolerance of 30 to 50 ppm. The resonator, on the other hand, is not as precise as crystal, because it comes with an understanding of just 1percent. Another difference is on the temperature stability of the two.

Crystal has a temperature stability of 0.005 percent, while resonator comes to the temperature stability of 0.1 percent. In terms of sensitivity, crystal is more sensitive than resonator. If the basis of our comparison is on their size, crystal is relatively larger than resonator, this means, resonator comes with a smaller size. Also, the resonator is easy to build, but the crystal is a little bit hard to make.
