f/f (PPM)
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) ²
= -0.04 PPM x (20) ²
= -16.0 PPM
ELECTRICAL CHARACTERISTICS

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.
