Overview of Oscillators

Oscillators are important electronic components that are widely used in a variety of applications, ranging from audio and communication systems to power supplies and motor speed drives. Oscillators generate periodic signals which are used to control the operation of other electronic components. Oscillators also play a key role in the operation of AC circuits. In this article, we will discuss the application field and working principle of one type of oscillators--the 353TB5A135T, manufactured by Intersil. We will briefly review the different types of oscillators, explain the application field and working principle specific to the 353TB5A135T and provide some examples of applications.

Types of Oscillators

Oscillators can generally be classified into two main categories based on the type of signal they generate--analog and digital. Analog oscillators generate a continuous, sinusoidal waveform, while digital oscillators produce a square waveform.Analog oscillators are commonly used in audio systems, such as radios and speaker systems. They are also used to synchronize the frequency of energies in mobile networks. Digital oscillators are used in applications such as computers and microprocessors where a square waveform is preferred.

The 353TB5A135T Oscillator

The Intersil 353TB5A135T is a digital oscillator designed primarily for use in communication systems. It has a small profile with an operating temperature range of -40°C to 85°C. It also has a low power consumption of only 0.6 V. The 353TB5A135T generates a square waveform with a frequency of 135 kHz. This frequency can be adjusted by using an external resistor. Additionally, there are on/off pins that can be used to control the oscillator’s output frequency.

Working Principle

The 353TB5A135T employs a VCO (voltage controlled oscillator) topology to generate its output signal. The VCO is essentially a type of amplifier with an internal feedback loop that generates a frequency-dependent sine wave output.This makes it possible to adjust the output frequency accurately by varying the input voltage. In the 353TB5A135T, this is achieved by altering the voltage drop across the external resistor. The on/off pins are also used to control the output, aiding in synchronization and noise reduction.

Applications

The 353TB5A135T is most commonly used in communication systems. Its small profile and low power consumption makes it ideal for applications where space and power consumption are a concern. Additionally, its frequency range is well-suited for use in data transmission and synchronization in LANs and backbones.The oscillator is also used in surveillance systems and other consumer electronics, such as televisions, DVDs and Blu Ray players. Additionally, it has been used to generate the clock signals for some memory modules and microprocessors.

Conclusion

In this article, we have discussed the application field and working principle of the Intersil 353TB5A135T oscillator. We have also outlined its features and provided some examples of applications. The 353TB5A135T is a small profile, low power consumption digital oscillator that is well-suited for use in communication systems and other consumer electronics.
