Crystal Oscillator 32.768 khz
A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a quartz crystal to create an electrical signal with a very precise frequency. The 32.768 kHz crystal oscillator is a common type of oscillator used in electronic devices that require a precise timekeeping function, such as watches, clocks, and microcontrollers.
The frequency of 32.768 kHz is significant because it is precisely 2^15 cycles per second, which makes it a convenient frequency to use in digital circuits. In addition, it is also a low frequency that can be easily divided down to create slower clock signals that are used by the internal logic of the device.
The quartz crystal used in a 32.768 kHz oscillator is typically a small, flat disk that is cut to a precise size and shape. When an electrical signal is applied to the crystal, it vibrates at a very specific frequency, which can be used to generate a stable clock signal.
