Housing for the ECX-205/ 206 crystal is
made from the same thermoplastic that
is industry standard for integrated
circuits. This ruggedized molded
package is excellent for SMD
applications.

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
