The miniature ECX-26 and the sub-miniature
ECX-15 are compact, cost effective SMD
tuning fork crystals. The slimline molded
package requires less space than other SMD
tuning fork crystals.

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

(As required)
C1 = 22pF, C2 = 22pF, VDD = 3.0V
In this circuit, low
drive level with a
maximum of 1W
is recommended.
If excessive drive
is applied, irregu-
lar oscillation or
quartz element
fractures may
occur.
