Tuning Fork Crystal
FEATURES
The tuning fork type quartz crystal provides ultimate in size,
performance and economic trade-offs. So it is used as a
clock source in communication equipment, measuring
instrument, microprocessor and other time management
applications.

∆F/f (ppm)
To determine frequency stability, use parabolic curvature (k).
For example: What is stability at 45 °C?
1) Change in Temperature (°C) = 45 - 25 = 20 °C
2) Change in Frequency = - 0.042 ppm*(Δ°C)
= - 0.042 ppm*(20)2
= - 16.8 ppm (max)
