Clock pulse generator / binary counter

Clock pulse generator / binary counter
This digital circuit (CD 4060) allows to produce a stable square signal of high frequency by means of a quartz and very few secondary components. Its counter function (divide by 2 counter) allows to find one frequencies suited for the clocks of the CCD.

Components List
Resistor : R1 = 10 MΩ
Capacitors : C1, C2 = 4.7 pF
Quartz : X1 = 12 MHz
digital circuit : CD 4060
Power supply VCC : 5 to 18 V
Output Qi delivers a frequency equal to the quartz frequency divided by 2 at the power i (ex: Q5 gives Freq / 32)
