SIT9120AI-2D-25S

Programmable oscillators are electrical components often used in signal or data generation. Their primary objective is to provide controlled, stable signal outputs that can be adjusted depending on the application. SIT9120AI-2D-25S, specifically, is a dual-output, 25MHz adjustable frequency programmable oscillator. It is a low jitter device with an excellent RF performance with the power supply it requires.

As the name implies, a programmable oscillator can be programmed for different frequencies and output forms. The SIT9120AI-2D-25S is designed with an output range of 0.5MHz to 19MHz and a wide VCO range of 380MHz to 620MHz. It also offers a range of frequency stability options, such as 0.5PPM, 2PPM, 5PPM and 10PPM, to match system requirements. The frequency and phase stability of the SIT9120AI-2D-25S can be adjusted by setting the capacitance from a wide range of options with its external capacitor-only configuration. With an internal 2.5V voltage regulator, the oscillator operates at well below 1.0mA current and 350nA standby current.

SIT9120AI-2D-25S is mainly used in radio frequency (RF) applications, transmitter/receiver systems and transmit/receive loop systems. For example, in a transmitter/receiver system, it can be used to generate the necessary clock signals. Its adjustable frequency and excellent RF performance makes it a suitable choice for frequency-hopping systems. In a system with a transmit/receive loop, the SIT9120AI-2D-25S can be used to generate the necessary clocking signals for both the transmit and receive paths.

The working principle behind the SIT9120AI-2D-25S is the same as that of most other oscillators. It is designed to generate an output voltage or current waveform at a predetermined frequency. The frequency is determined by the oscillator’s internal resonator, which is usually an LC (inductor-capacitor) oscillator circuit. The resonator is triggered by an external voltage source, which helps to provide the necessary power for the oscillator to oscillate. By changing the values of the capacitors in the resonator, the output frequency can be adjusted.

The SIT9120AI-2D-25S is a very efficient and reliable programmable oscillator. With its adjustable frequency and excellent RF performance, it is a suitable choice for a wide range of applications. It is also easy to program and configure, making it very user-friendly and versatile.
