In this circuit, low drive level with a maximum

of 1µW is recommended. If excessive drive is

applied, irregular oscillation or quartz element

fractures may occur.

To determine frequency stability, use parabolic

curvature. For example:

What is the stability at 45˚C?

1) Change in T (˚C) = 45 -25 = 20˚C

2) Change in frequency = -0.04 PPM x (ΔT)

= -0.04 PPM x (20)

= -16.0 PPM
