ECS-3X8X, 2X6X, 1X5X

32.768 KHz TUNING FORK

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.

FEATURES

• Cost effective

• Tight tolerance

• Long term stability

• Excellent resistance and

environmental characteristics

• PbFree/RoHS Compliant

In this circuit, low drive level with a maximum of 1µW is rec-

ommended. If excessive drive is applied, irregular oscillation

or quartz element fractures may occur.

To determine frequency stability, use parabolic

curvature. For example: What is the stability at 45˚C?

1) Change in T (˚C)

2) Change in frequency
