Programmable Oscillators are a form of oscillator designed mainly to maintain communication with a transmitter and receiver, or two receivers when used in tracking systems. Depending on the model, the oscillator can be used to generate specific frequencies or to maintain a user-defined frequency within an acceptable range. This makes them quite useful in diverse applications, particularly where precise frequency control is necessary while at the same time keeping power consumption low.

One of the most popular types of programmable oscillators is the SIT9005ACT2H-XXNE. This model is a voltage-controlled oscillator (VCO) that is widely used in different industries, such as communications, aviation, and military, for timing synchronization. It is capable of providing high-precision tuning and maintaining cutting-edge performance over wide-band frequencies and temperature ranges.

This oscillator facilitates a wide variety of applications with its comprehensive tuning capabilities. It offers a frequency range from 10 kHz to 10 GHz, making it suitable for fixed and swept frequency applications. It can be used for frequency-agile communications, frequency hopping, and wide area frequency coordination. Furthermore, the SIT9005ACT2H-XXNE has an exceptionally low phase noise of -87 dBc/Hz, hence, providing low out of band distortion. This makes it ideal for communication systems that require good signal-to-noise ratio.

The working principle of the SIT9005ACT2H-XXNE is based on producing oscillations in a loop circuit. It consists of a voltage-controlled oscillator (VCO), a varactor diode, a phase detector, and a voltage-controlled amplifier (VCA). The VCA is used to vary the level of the phase-detector’s output voltage, which in turn controls the frequency of oscillations.

The VCO is linked to the varactor diode and phase detector. The VCO generates an AC signal at the frequency determined by the frequency control voltage. The signal is fed to the varactor diode and the phase detector. The signal generated by the phase detector is fed to the VCA. The VCA amplifies or attenuates this signal depending on the control voltage that it receives. This causes the signal to be continuously compared with the VCO’s signal, hence, the VCO’s oscillation frequency is adjusted accordingly.

The SIT9005ACT2H-XXNE is an ideal candidate for a range of frequency control applications and its wide frequency range, low phase noise, and robust construction make it very reliable in harsh environments. The device is compatible with most circuit boards and systems, making integration effortless for designers and engineers. Additionally, the device can be programmed to different operating modes, allowing for greater flexibility in applications. By taking advantage of these features, the SIT9005ACT2H-XXNE can be used in a variety of applications, including frequency hopping, frequency agile communications, wide area frequency coordination, and RF tracking systems.
