Oscillators are electronic devices used to generate a continuous ac voltage or current. The common oscillator types are sine wave, saw-tooth, square wave, and triangular wave oscillators, voltage-controlled oscillators (VCOs), and phase-shift oscillators. A key advantage of oscillators is that they can be used to create signals that are difficult or impossible to generate using conventional means such as transistors, diodes, and resistors. In this article, we will take a look at the application field and working principle of one oscillator, the 653L21256A3T.

Application Field of the 653L21256A3T

The 653L21256A3T is a medium frequency oscillator with frequency ranging from 5kHz to 90kHz. This device is suitable for use in a variety of communication and control applications, such as telephone communication systems, wireless communication systems, cellular phones, personal digital assistants (PDAs), modems, radios, remote control systems, motor controls, automatic data scanners, security systems, and more. It has a wide frequency range, low power consumption, low phase noise, excellent temperature characteristics, and high reliability.

Working Principle of the 653L21256A3T

The 653L21256A3T oscillator is based on two main components: a quartz crystal and an oscillating circuit. The quartz crystal is a piezoelectric element, meaning that it vibrates when an electric field is applied to it. The frequency of oscillation is determined by the physical characteristics of the crystal, such as its shape and size. The oscillating circuit is used to generate a sinusoidal output waveform. In the 653L21256A3T, this is done by three stages, each producing a slightly different waveform. The first stage produces a square wave, which is then filtered and shaped into a sine wave by the subsequent two stages.

The frequency of the 653L21256A3T is determined by the frequency of the quartz crystal. The frequency can be changed by changing the value of resistor or by using a voltage-controlled oscillator circuit. The amplitude of the output waveform is determined by the supply voltage and can be adjusted using an adjustable resistor. The output impedance is fixed and dependent on the load impedance. The 653L21256A3T is designed for use in environments up to 85°C.

The 653L21256A3T is a highly reliable, low-cost oscillator suitable for a various range of applications. It has a wide range of frequencies, a low power consumption, and excellent temperature performance. It is a robust and reliable device, making it a popular choice for many communication, control, and monitoring applications.
