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.

(OUTPUT)
1.F Outputs the original frequency (fo) of the internal quartz crystal.
2.D Outputs the frequency of
programmed dividing ratio (fo/2n).
3.ST 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 Used to program the divid-
7.C ing ratio for the original frequency.
8.VDD Supply voltage
