Description
The KSS-EXO-3 is a super-small CMOS crystal clock
oscillator in an 8-pin dip package equipped with a
8
Programmable Frequency Divider. Division 1/2 to 1/2
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.

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.
