Programmable Oscillators: SIT9005ACT2G-18SG Application Field and Working Principle.Oscillators are important components in many electronic applications ranging from data acquisition to communication systems. Oscillators have the ability to generate an electric current that oscillates at a given frequency. They are used to generate periodic signals, create clock pulses and provide timing references for digital circuits.Programmable oscillators are a type of oscillator that can be programmed to produce a specific frequency or set of frequencies. These programmable oscillators are used in a variety of applications, such as radio communication systems, data acquisition systems, frequency-controlled motors, and power supply systems.Among programmable oscillators, the SIT9005ACT2G-18SG is the most commonly used. It is a low-cost, low-power, high-performance programmable oscillator. The SIT9005ACT2G-18SG features a 14-pin DIP package, adjustable operating temperature range, and an excellent accuracy of ±0.2 ppm with a frequency range of 1.2 MHz to 37.0 MHz.The SIT9005ACT2G-18SG is primarily used in telecommunications, data-acquisition and control systems. It is particularly suitable for applications where a fixed frequency is desired, but where cost and size must be minimized. Its relatively low cost and small size make it particularly attractive to tight-budget applications.In addition, the SIT9005ACT2G-18SG is also used in automotive applications, such as engine control, transmission control and audio systems. It is well suited for these applications due to its extended temperature range.The working principle of the SIT9005ACT2G-18SG is based on the oscillation of an inductor with a capacitance in parallel. This configuration creates an LC (Inductance-Capacitance) tank circuit that resonates at a frequency based on the values of the inductor and capacitor. The inductor is connected to an external resistor, which determines the oscillation frequency.The SIT9005ACT2G-18SG has an adjustable frequency range from 1.2 MHz to 37.0 MHz. The frequency can be adjusted using the external resistor. The oscillator can be programmed using the digital control registers on the chip. Once the desired frequency is programmed, the oscillator will generate a sinusoidal output at that frequency.In conclusion, the SIT9005ACT2G-18SG is a low-cost, low-power, high-performance programmable oscillator suitable for a range of applications, including telecommunications and data-acquisition. Its adjustable frequency range, small form-factor and extended temperature range make it suitable for automotive, as well as industrial applications. The working principle of the SIT9005ACT2G-18SG is based on an LC tank circuit that is adjusted using an external resistor. Once programmed, the SIT9005ACT2G-18SG can generate a sinusoidal output of a desired frequency.
