ECX-205/206 SMD TUNING FORK CRYSTAL
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.
FEATURES
• Low profile
• Long term stability
• Industry standard footprint
• Tape and Reel (2,000 pcs)

Rd: 330KΩ (As required)
C1 = 22pF, C2 = 22pF
VDD = 3.0V
In this circuit, low drive level with a maximum of
1µW is recommended. If excessive drive is
applied, irregular oscillation or quartz element
#3 fractures may occur.
#2
To determine frequency stability, use parabolic
curvature. For example: What is the stability at 45˚C?
1) Change in T (˚C) = 45 -25 = 20˚C
2) Change in frequency = -0.04 PPM x (∆T)2
= -0.04 PPM x (20)2
= -16.0 PPM
