Programmable Oscillators
Programmable oscillator are a versatile device which can be used in a variety of applications. They are designed to provide a reliable, fixed frequency, with frequency change capabilities. SIT9003AI-2-33SB is one such oscillator and can be used in a wide range of applications. This article discusses the functions and features of the SIT9003AI-2-33SB and its applications, as well as its working principle.Function and Features
The SIT9003AI-2-33SB is a programmable oscillator with a frequency range of 250kHz to 40 MHz, and a temperature stability of ± 1.5 ppm from -20 to 85°C. Its temperature stability is achieved by a voltage-controlled oscillator (VCO) that combines the temperature-compensated oscillator (TCXO) and a charge pump. It has an output waveform of sinusoidal waveform with adjustable frequency and a wide operating voltage range of 1.8 to 3.3V. It even offers voltage and temperature compensation and also enables the users to select a low-noise output.Applications
The SIT9003AI-2-33SB is ideal for use in many applications such as high-speed wireless backhaul and wireless broadband applications, including digital radio, femto base station receivers, and next-gen wireless modems. It can also be used in WLAN (Wireless Local Area Network) and Wi-Fi (Wireless Fidelity) applications, as well as in audio-frequency applications.Due to its high frequency range and temperature stability, the SIT9003AI-2-33SB is ideal for use in automotive applications, in particular in automotive communication systems, including mid- and long-range radar. It can also be used in industrial and medical applications, such as automotive safety systems, as well as medical and process control systems.Working Principle
The SIT9003AI-2-33SB works on the principle of voltage-controlled oscillator (VCO) technology. In this type of oscillator, the frequency is determined by the control voltage, which can be adjusted over a wide range. The oscillator consists of a quartz crystal resonator, a voltage-controlled amplifier, and a capacitor to generate the oscillations.The VCO consists of an inverter, a switching transistor and a voltage-controlled capacitance. The inverter and transistor operates in the linear mode, in which the voltage across the transistor can be varied between zero and the supply voltage. This makes the oscillator sensitive to temperature, so temperature compensation is necessary for better temperature stability.The frequency of the oscillations can be adjusted by controlling the transistor\'s current density and hence the oscillator\'s capacitance. The frequency of the oscillations can also be adjusted by varying the tuning voltage, which influences the capacitance of the oscillator. This frequency adjustment allows the SIT9003AI-2-33SB to give a stable output frequency over a wide temperature range.In conclusion, the SIT9003AI-2-33SB is an ideal programmable oscillator for applications that require highly stable frequency signals over a wide temperature range. It is a versatile device that has a wide range of applications in the automotive, industrial, medical and communication fields.The specific data is subject to PDF, and the above content is for reference
