Oscillators: 653L18755I2T Application Field and Working Principle

Oscillators are electronic components or circuits that generate periodic signals in a sinusoidal or triangular waveform. They are essential in the field of digital electronics and communication systems, providing an accurate source of time-varying signals to control the timing and operation of the digital systems. Oscillators are widely used in wireless communication systems such as radio, televisions, GPS, mobile phones, radios, etc., as they provide a rapid transmission of data with intime accuracy. The 653L18755I2T is one of the most advanced oscillator products available in the market today. This article details the application field and working principle of the 653L18755I2T.

653L18755I2T Applications

The 653L18755I2T is a low power, low noise, 3.3V oscillator providing an output frequency ranging between 0.28 to 66 MHz. It is ideally suited for communication applications including mobile phones, digital television sets, wireless networks, and global positioning systems. The 653L18755I2T is also suitable for data processing, test and measurement, industrial control equipments, gaming, digital broadcast systems, and office automation. It is designed to meet all safety, electromagnetic compatibility, environmental, and reliability requirements from the industrial/office equipment sectors.

The 653L18755I2T consists of a frequency-select circuitry which is coupled with an oscillator multivibrator circuit and an amplifier circuit. The frequency-select circuitry allows a user to select a frequency within the range of 0.28 to 66 MHz by adjusting the appropriate values of capacitors and inductors. The oscillator multivibrator circuit consists of complementary NMOS transistors, which act as an astable multivibrator. Two outputs generated from the complementary transistors create a symmetrical square waveform. The amplifier circuit amplifies the output of the multivibrator circuit to higher levels, thus providing an output in accordance to the selected frequency.

653L18755I2T Working Principle

The 653L18755I2T oscillator works by providing two complementary outputs generated by an astable multivibrator circuit. The transistor stage acts as an amplifier for both positive and negative voltage levels. First, a resistor-capacitor (RC) network is connected to the collector of a first transistor whose base is driven by a voltage source. The capacitor of the RC network is charged at its maximum capacity whenever there is a change in the voltage level of the voltage source.

The energy storing capacitor then begins to discharge itself through the resistor of the RC network. This creates an oscillation in the waveform, resulting in the changing of the collector voltage of the first transistor. The output of the first transistor is then sent to the base of the second transistor acting as an inverting amplifier which inverts the output of the first transistor. This inversion of voltage is necessary as the incoming frequency signal cannot be used directly by any other electrical circuit. Both the outputs of the first and second transistors form a symmetrical square waveform at the oscillator\'s output.

The output voltage level depends on the values of the external resistors and capacitors. The oscillator frequency varies accordingly and is determined by the selected values of the resistors and capacitors. The 653L18755I2T oscillator adjusts itself to frequencies in between 0.28 to 66 MHz by using this technique. It is also a low power consuming oscillator with an operating frequency of up to 1MHz and a low current consumption of 1.5 mA.
