Cirrcuit Schematic 50 Hz 60 Hz Frequency Generator using Crystal Oscillator

Generator. - Here is Cirrcuit Schematic 50 Hz 60 Hz Frequency Generator using Crystal Oscillator. You can generate 50Hz or 60Hz using this frequency generator. This oscillator can be used as the front end of circuits that require precision pulses.

A crystal is used in the circuit to generate clock pulses. The circuit uses two counter ICs CD4060 and 7490 to divide the basic frequency to generate 50Hz or 60Hz pulses.
