Programmable oscillators are oscillators which allow users to set the frequency and other parameters such as duty cycles and timings of their signals. The SIT9002AI-48H33DX is a type of programmable oscillator that is able to meet the ever-increasing demands for frequency control in various industries. This article will discuss the application fields and working principles of the SIT9002AI-48H33DX.

Application Field of SIT9002AI-48H33DX

The SIT9002AI-48H33DX is mainly used in high-speed communications, military and aerospace. With this device, engineers need not worry about maintaining an accurate frequency throughout the entire process. In addition, it is suitable for numerous applications due to its versatile and wide frequency range,which can range from 48-72MHz.

The oscillator is also suitable for communication channels with a very high data rate such as long distance radio links, Digital Video Broadcasting (DVB), CDMA and TDMA. It is also ideal for various industrial applications such as servo motors,encoders and robotic sensors. Moreover, the oscillator is used to measure parameters such as speed and torque in industries.

This device is particularly useful for frequency hopping applications such as military communications, a technology used for reducing interference and jamming. By hopping from one frequency to another on a regular basis,frequency hopper radios deny an enemy the opportunity to intercept the transmission. This makes the SIT9002AI-48H33DX very attractive in many military applications.

Working Principle of SIT9002AI-48H33DX

The SIT9002AI-48H33DX is a voltage controlled oscillator (VCO) that uses a voltage control input to generate an oscillating signal. The VCO allows the user to set the frequency,duty cycle, and timing of the signal by adjusting the applied voltage. It is based on an integrated circuit known as a Frequency-Locked Loop(FLL) and uses a bipolar transistor to amplify the signal.

The FLL is a closed loop system, meaning that the output signal frequency is directly proportional to the input voltage. The voltage determines the speed of the oscillator, which affects the output frequency. When the voltage is increased, the speed of the oscillator increases, resulting in a higher output frequency. Conversely, when the voltage is decreased, the speed of the oscillator slows down, resulting in a lower output frequency.

In addition to controlling the signal frequency, the FLL also controls the duty cycle and timing of the signal. Duty cycles and timing refer to the amount of time a signal is switched on and off. By changing the voltage input, the user can adjust the signal duty cycle and timing. This allows the user to fine-tune their signal according to their application requirements.

The SIT9002AI-48H33DX is a versatile programmable oscillator for use in many applications. It offers wide frequency range, precise timing and duty cycle, and is highly reliable. The working principle of this device makes it a great choice for applications requiring frequency hopping, such as military communications.
