Crystal Oscillator
- 58 -
EXO-3
CMOS Crystal Oscillator
Features
Since it has a frequency dividing function, it is able to obtain a frequency division of
1/2-1/2
8
(1/256).
The symmetry of frequency divided output is within 50 plus/minus 2%.
The oscillation start time has the fast starting characteristic of being 1.5msec. or less.
The pin arrangement is DIP 8PIN.

Outputs the original fre-
quency (fo) of the internal
quartz crystal.
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.
Used to program the divid-
ing ratio for the original fre-
quency.
