KSS-EXO-3 Series
Dimensions (mm)
Pin Connections
1.F
Outputs the original frequency (fo) of the internal quartz
crystal.
2.D
Outputs the frequency of programmed dividing ratio (fo/2
n
).

Possible to be oscillated when set to HIGH level and
stopped in oscillation when set to LOW level. When this
function is not needed, be sure to set the STANDBY pin to
the HIGH level.
4. Gnd
5.A, 6.B & 7.C
Used to program the dividing ratio for the original frequency.

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 1/2to 1/2
8
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 0.01µF) 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.
