Background

In electronics, an oscillator is an electronic circuit that produces a continuous periodic wave of alternating voltage, current, or any other type of desired waveform. Oscillators can be broadly classified into two types, analogue and digital. The 579S260ITT oscillator is a Digital Tilt Finite Impulse Response (FIR) filter based Digital oscillator. It is designed to meet the specific demands of the industrial, aerospace, and automotive applications.

Application field

The 579S260ITT oscillator can be used widely in a variety of applications such as signal processing, video and audio processing, digital signal processing (DSP), radar, sonar, communications, telemetry, and so on. The output of the oscillator can directly interface with programmable logic devices such as micro-controllers, various memory systems, analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).

Working Principle

From the working principle point of view, the 579S260ITT oscillator utilizes the Digital Tilt Finite Impulse Response (FIR) filter technique. It consists of two separate sections. The first section is the Tilt Compensator which is used to stabilize the output of the oscillator. The Tilt Compensator and the Phase Detector are the two main components in the second section which determines the output signal phase. The output signal of the oscillator is directly coupled to the input of the Tilt Compensator. This compensates any phase shift in the output signal. The output of the Tilt Compensator is then fed into the Phase Detector. The input of the Phase Detector is compared to the reference input. If there is any difference in the phase, an error signal is generated which adjusts the phase for the next cycle. This process is repeated and the output of the oscillator is stabilized.

Conclusion

In conclusion, the 579S260ITT oscillator is a digital Tilt Finite Impulse Response (FIR) based oscillator that can be used for a wide range of applications such as signal processing, video and audio processing, digital signal processing (DSP) and so on. This oscillator utilizes the Digital Tilt Finite Impulse Response (FIR) filter technique to stabilize the output signal. The output of the oscillator can directly interface with a variety of programmable logic devices and memory systems.
