Description
The KSS-EXO-3 is a super-small CMOS crystal clock
oscillator in an 8-pin dip package equipped with a
Programmable Frequency Divider. Division

simultaneously with the original frequency can be achieved
at the user's freedom with this revolutionary device.
Composed of an AT-cut oscillator and a specially designed
CMOS IC divider, this device realises a wide range of
supply voltage, lower power consumption, high speed
operation and provides a standby function to meet most of
the user's needs. This extraordinary device can utilise
various pick & place machinery, replacing traditional
oscillators.

Handling Notes
Since this KSS-EXO type crystal clock oscillator employs a
CMOS IC integrated with a protection circuit for static
electricity, please handle only in an anti static environment.
No by-pass capacitor is inserted between the power supply
stage (V
DD
-Gnd). To protect from overvoltage and
overcurrent due to power supply noise, provide a capacitor
(above 0.01F) as close as possible to the V
DD
-Gnd pin.
If V
DD
is applied to Pin 4, a Gnd pin, mistaken as Pin 8 (V
DD
),
ot an inverse current is applied to the device, it casuses an
internal destruction or no oscillation in some cases. To avoid
this, strict care should be taken over correct pin connection.
