Pulse Generator Oscillator 32.768KHz by watch crystal

A friend requires a pulse generator oscillator circuit that maintains a stable frequency of 32.768 kHz for a digital CMOS binary counter.

The pulse generator oscillator circuit designed to operate at a frequency of 32.768 kHz is commonly used in digital applications, particularly in timing devices and binary counters. This frequency is significant as it is derived from the division of the standard clock frequency of 2^15 Hz, making it ideal for applications such as real-time clocks and timers.

The circuit can be implemented using a variety of components, such as a crystal oscillator, which provides high stability and accuracy. A typical configuration includes a crystal resonator of 32.768 kHz, which is connected to an inverter or a CMOS oscillator IC. The inverter amplifies the signal and ensures that the output waveform is a square wave, suitable for driving the digital CMOS binary counter.

In addition to the crystal, passive components like resistors and capacitors are used to set the oscillation conditions. The selection of these components is crucial to achieve the desired frequency stability and waveform characteristics. For example, a capacitor may be connected in parallel with the crystal to enhance the stability of the oscillation.

The output of the pulse generator is typically a square wave signal, which can be fed directly into the clock input of the CMOS binary counter. This allows the counter to increment its value with each pulse, effectively counting in binary format. The design should also consider power supply requirements, ensuring that the circuit operates efficiently within the specified voltage range for the CMOS components.

Overall, this pulse generator oscillator circuit provides a reliable solution for generating a stable 32.768 kHz frequency, fulfilling the requirements of digital CMOS binary counters and other timing applications.My Friend need to like a Pulse Generator Oscillator circuit that stable frequency at 32.768KHz,for digital cmos binary counter, so he tell to me even low.. 🔗 External reference
