Programmable oscillators are electronic components designed to generate active electronic signals in specific frequencies and amplitudes. The SIT3822AC-2D-25NE is an example of such oscillator, and it is designed for use in high-frequency circuit applications. In this article, we will discuss the application field and working principle of SIT3822AC-2D-25NE.
Application fieldThe SIT3822AC-2D-25NE is a programmable oscillator covering frequencies from static (DC) to 2.2GHz, with a resolution of 0.1% or better. It is suitable for a variety of applications, such as frequency synthesizers, clock circuits, signal generators, modulators and demodulators, and RISC (Reduced Instruction Set Computer) systems.
This programmable oscillator is designed for use in a wide variety of digital communications applications, including cellular phones, wireless LANs, broadcast audio, digital television and data transmission. This oscillator is also suitable for military, medical, scientific and instrumentation applications.
Working principleThe SIT3822AC-2D-25NE functions as a dual-frequency oscillator, employing two independent programmable frequencies in one device. The oscillator\'s frequencies are controlled by two signals: a program control signal and a voltage control signal. The program control signal is used to set the target frequency, and the voltage control signal is used to adjust the target frequency.
The SIT3822AC-2D-25NE utilizes an oscillator design which utilizes a feedback loop made up of an active component and a capacitor to create an oscillating signal. The active component is usually an amplifier, and the capacitor provides negative feedback. The output of the oscillator is a periodic wave, with a frequency determined by the values of the active component, the capacitor, and the frequency of the program control signal.
The SIT3822AC-2D-25NE also incorporates an auto-calibration circuit, which is designed to ensure that the oscillator starts and maintains a frequency within its programmed limits. The frequency is then adjusted using the voltage control signal. This ensures that the SIT3822AC-2D-25NE can perform as expected in its intended applications.
In summary, the SIT3822AC-2D-25NE is a programmable oscillator suitable for a variety of high frequency applications. It utilizes a feedback loop with an active component and capacitor to generate an oscillating signal, and incorporates an auto-calibration circuit to ensure the frequency is within its programmed limits. This makes the SIT3822AC-2D-25NE ideal for applications in digital communications, military, medical, scientific and instrumentation uses.
