Crystal Oscillator
EXO-3
CMOS Crystal Oscillator
■Features
¡Since it has a frequency dividing function, it is able to obtain a frequency division of
1/2-1/28 (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.
