Housing for the ECX-306/ 306I crystal is
made from the same thermoplastic that
is industry standard for integrated cir-
cuits. This ruggedized molded package
is excellent for SMD applications.

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

RECOMMENDED OSCILLATION
CIRCUIT
In this circuit, low
drive level with a
maximum of 1μW
is recommended.
If excessive drive
is applied, irregu-
lar oscillation or
quartz element
fractures may
occur
