Programmable OscillatorsProgrammable oscillators, also known as Digital Oscillators, are a specialized form of oscillators which allow for the precise programming of a variety of parameters, such as center frequency, frequency tolerance, output power, package size, and other parameters. These oscillators are used in a variety of applications and are widely employed in modern day electronics. One example of a programmable oscillator is the SIT9002AC-38H18EB. This oscillator is designed to operate in harsh environments, such as those found in some industrial applications. It has a wide frequency range of 36MHz to 38MHz. It has an adjustable band-width of 1MHz, allowing for precise frequency tuning. To understand the working principle of this oscillator, we must first understand what an oscillator is. An oscillator is an electronic device which generates periodic electrical signals. In its simplest form, an oscillator consists of an amplifier and one or more resonant circuits. The amplifier amplifies the signal as it is transmitted through the resonant circuits. The SIT9002AC-38H18EB incorporates an adjustable phase-locked-loop (PLL) circuit which is used to provide the precise frequency control. The PLL uses a voltage-controlled oscillator (VCO) to generate the desired output frequency. Through the use of several subsystems, the PLL is able to precisely adjust the frequency of the output. The oscillator also employs a digital frequency synthesizer which provides precise control of the output frequency. This digital synthesizer uses a digital-to-analog converter (DAC) to generate the desired output frequency. The frequency is then amplified in the following stages of the PLL circuitry.The SIT9002AC-38H18EB is designed for use in a variety of industrial and commercial applications. It is especially suitable for use in communication and measurement equipment, such as radio receivers and transmitters. It is also suitable for use in medical and industrial applications, as well as for laboratory and research applications.Some of the features of this oscillator make it particularly suitable for these applications. It has a wide operating temperature range, from -5C to +85C. It is also extremely stable with an excellent noise performance. The package size is 7.5mm x 5.16mm x 1.5mm.Overall, the SIT9002AC-38H18EB is a versatile and reliable programmable oscillator which can be used in a variety of applications. It is designed to operate in harsh environments and has a wide frequency range and excellent performance. Its adjustable phase-locked-loop circuit and digital frequency synthesizer provide precise control over the output frequency. This makes it ideal for use in industrial and commercial applications such as radio receivers and transmitters, medical and industrial applications, and laboratory and research applications.
