This circuit was obtained from an American 1980s documentation. The frequency depends on the crystal and the circuit may be a PNP that reaches the generated frequency.
Found in an Electronics World of 1966 this circuit can be made with current power transistors. It causes...
This simple clock can be used to generate signals up to 100 kHz, depending on the crystal. We found...
We found this circuit in a 1964 Electronic Design. It divides the frequency of a 20 MHz signal by...
