In this circuit, low drive level with a maximum of
1µW is recommended. If excessive drive is
applied, irregular oscillation or quartz element

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 (∆T)²
= -0.04 PPM x (20)²
= -16.0 PPM
