Programmable oscillators are electronic components with one or more variable frequency outputs that have the ability to be programmed to multiple frequencies. The SIT8008BCL3-28S is a programmable oscillator that has the capability to offer flexibility for a wide range of applications. In this article, we will examine the SIT8008BCL3-28S and its applications and working principles.The SIT8008BCL3-28S is a low power, highly integrated crystal oscillator in a 28-pin LQFP package. It is ideally suited for applications such as mobile phones, portable gaming devices, laptops, digital cameras, and other modern applications. This programmable oscillator offers a low power and frequency range of 16kHz to 1200kHz.In terms of its features, the SIT8008BCL3-28S has high integration, low power, small size and high precision. The oscillator produces a low phase noise signal, an accuracy as low as + / - 5ppm and an excellent pull range of +/-50ppm up to +/-1000ppm.In terms of its applications, the SIT8008BCL3-28S can be used for applications such as phase locked loops (PLL), clock generator, frequency synthesizers, and other clock related applications. The oscillator can also be used for low power applications where frequency stability and accuracy are required.Regarding its working principle, the SIT8008BCL3-28S is built upon an electronic oscillator circuit including an Integrated Circuit (IC), an oscillator frequency reference, and a digital controller. The IC is responsible for providing the desired frequency output and the digital controller is responsible for modifying the frequency of the output signal.Other components of this oscillator include a voltage regulator, a charge pump and a high-speed CMOS multiplexer which provide the power supply and the clock signal, respectively. The voltage regulator provides a stable output voltage, while the charge pump is used to supply the controller with a steady supply of electricity even during dynamic frequency changes.The internal components of the SIT8008BCL3-28S are divided into two parts. The first part, which includes the high-speed CMOS multiplexer, is responsible for transforming the reference signal from the frequency reference circuit into a digital form. The second part consists of the phase locked loop (PLL), which is responsible for controlling the oscillator’s phase and frequency.The PLL’s main job is to provide the oscillator with the desired frequency and stability. It does this by comparing the frequency and phase of the input signal to a reference signal and then modulating the voltage of the output signal to match the reference. This modulation of the output is done by changing the gain of the oscillators.To summarize, the SIT8008BCL3-28S is a programmable oscillator with features such as low power, small size, high accuracy, and excellent pull range. Its applications include phase locked loops, clock generators and frequency synthesizers, as well as low-power applications requiring frequency accuracy and stability. Its working principle is based on an oscillator circuit including an IC, a reference signal and a digital controller.
