Clock pulse generator / binary counterThis 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.
Pin Assignments for CD4060 Q12 Q13 Q14 Q6 Q5 Q7 Q4 Ground clk2 clk 1 clk reset Q9 Q8 Q10 +Vcc		Components ListResistor : R1 = 10 MΩ Capacitors : C1, C2 = 4.7 pF Quartz : X1 = 12 MHz digital circuit : CD 4060Power 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)
