Oscillators

Oscillators are electronic circuits that generate a continuous, repetitive electrical signal, called a sinusoid. They are widely used in many different electronic applications, from timing and clocking to motor control and communications. In this article, we will explore one type of oscillator, the ASHEK-32.768KHZ-LT, its application field and operating principle.

ASHEK-32.768KHZ-LT Oscillator Overview

The ASHEK-32.768KHZ-LT is a low power CMOS oscillator. It has a frequency accuracy of ± 50 ppm, and a frequency stability of how the oscillator works. The operating temperature range is from -10 °C to +70 °C, providing a wide range of options in the field of oscillator applications. It is highly versatile and can be used for a variety of tasks.

Application Fields

The ASHEK-32.768KHZ-LT oscillator is most commonly used as a timekeeper in digital watches and other timekeeping devices, such as pocket calculators or smart clocks. It is also useful for controlling the frequency of computer memory modules, as well as in robotic systems or digital circuitry applications. It can also be used as a frequency reference in applications such as frequency synthesizers, radio receivers, testers and modems.

Working Principle

The ASHEK-32.768KHZ-LT oscillator is based on a Colpitts oscillator configuration. It works by using two parallel capacitors, connected to a resistive load. The frequency of oscillation is determined by the capacitance and resistance of the load, and is determined by the equations:

F = 1 / 2π √ (C1 x C2) x R1

Where
F = Frequency of oscillation
C1 = Capacitance of capacitor one
C2 = Capacitance of capacitor two
R1 = Resistance of resistive load

The ASHEK-32.768KHZ-LT oscillator is designed to have a very precise frequency, and is able to maintain it despite variations in temperature or external electrical noise. This is achieved by using a temperature compensation method, which ensures that the oscillator operates at a stable frequency, even if the external conditions change. This helps to keep the oscillator running smoothly and reliably, providing accurate and consistent output.

Conclusion

The ASHEK-32.768KHZ-LT oscillator is a highly versatile and reliable oscillator, capable of providing a stable and accurate frequency despite variations in external conditions. It is most commonly used in digital watches and timekeeping devices, but can also be used in frequency reference applications and robotic systems. It works by using a Colpitts oscillator configuration and temperature compensation to maintain a consistent frequency output.
