Programmable Oscillators are essential components for any electronic circuit or device that requires precise frequency, timing or control signals. In recent years, the use of Programmable Oscillators has grown significantly thanks to advances in digital logic and embedded semiconductor technology. An attractive feature of such devices is that they are easy to integrate into circuits, making them ideal for a wide range of applications. One example of a Programmable Oscillator that is widely used in the electronics industry is the SIT3809AC-2-18EX, which is known for its reliability, accuracy, and affordability. This article will explore the application field and working principle of the SIT3809AC-2-18EX oscillator.

The most common application of the SIT3809AC-2-18EX oscillator is for generating time-base signals with its high accuracy clocks, frequency dividers, phase-locked loops and pulse-width modulation circuits. It can also be used for phase-shifting and frequency modulation. The device has a wide frequency range, from 0.5 to 200MHz, and is able to support a wide range of peripherals, making it ideal for many different applications.

The SIT3809AC-2-18EX oscillator also features excellent jitter performance, which is primarily due to its low phase noise, power dissipation and input-referred noise. The device can be programmed with an internal clock, an external source or both, giving it the flexibility to be used in a variety of applications. Additionally, the oscillator is temperature compensated and can be used in temperature extremes.

The SIT3809AC-2-18EX oscillator works on the principle of voltage-controlled oscillation (VCO) which is a type of electronic oscillator circuit where an input voltage is used to control the frequency or rate of oscillation. In the case of this oscillator, the input voltage is converted to a current control signal, which is then used to control the frequency of the device. This means that the oscillator can be programmed to output specific frequencies and can easily be reconfigured to operate at different frequencies.

The SIT3809AC-2-18EX oscillator is also designed with a built-in phase locked loop (PLL) which helps ensure that the oscillator remains locked in phase with an external reference of a known frequency. By using the PLL, any phase differences between the oscillator and the reference can be sensed and corrected, ensuring that the oscillator outputs the same frequency each time it is used.

The SIT3809AC-2-18EX oscillator is a versatile, reliable and cost-effective solution for many different applications. Its ability to be programmed with an internal or external clock and its wide range of supported peripherals make it ideal for applications such as radar systems, medical imaging, industrial process control, communications systems and automotive electronics. Additionally, the device\'s temperature compensation, wide frequency range and low phase noise make it suitable for all types of environmental conditions, from extreme temperatures to high vibration and shock. As such, the SIT3809AC-2-18EX oscillator is an excellent choice for designers looking for an oscillator with excellent performance and reliability.
