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.

RECOMMENDED OSCILLATION
CIRCUIT
PARABOLIC TEMPERATURE CURVE
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

T (C)
To determine frequency stability, use parabolic
curvature. For example: What is the stability at 45C
1) Change in T (C) = 45 -25 = 20C
2) Change in frequency = -0.04 PPM x (
T)
2
= -0.04 PPM x (20)
= -16.0 PPM
