ECS tuning fork type crystals are used as a
clock source in communication equipment,
measuring instruments, microprocessors and
other time management applications. Their
low power consumption makes these crystals
ideal for portable equipment.

In this circuit, low drive level with a maximum of 1µW is rec-
ommended. If excessive drive is applied, irregular oscillation
or quartz element fractures may occur.

T (˚C)
To determine frequency stability, use parabolic
curvature. For example: What is the stability at 45˚C?
1) Change in T (˚C)
2) Change in frequency
