200 kHz Oscillator (CB118)

A precision 200 kHz oscillator using a 32,768 kHz. caf crystal can be built with a 4080 IC as shown here. The frequency is divided by the sequence of flip-flops in the 4080, and a 200 kHz signal is the output. Other crystals can be used in this circuit [see the data-sheet for the 4080 to divide the crystal frequency by other numbers]. The trimmer capacitor is used to adjust the circuit before the power is turned on.
