Oscillators are specialized electronic circuits that when powered, alternately produce voltage and current cycles of positive and negative values, in order to guarantee stability in time and to keep a steady frequency over time. The SIT3821AI-2C3-33EE51.200000T oscillator is one of these electronic circuits designed to provide accurate and long-term stability, specifically for applications related to cellular communication, such as 5G. The oscillator functions in a variety of other applications, including servers, consumer electronic, automotive, and more. The SIT3821AI-2C3-33EE51.200000T is a quartz crystal oscillator, which is powered through an 8-pin LGA package. It has an adjustable frequency range of 0.7 to 50 MHz with a frequency stability of ± 0.3 ppm.
The working principle of the SIT3821AI-2C3-33EE51.200000T oscillator is the result of the piezoelectric effect. A piezoelectric effect is a type of physical effect when an electric charge is applied to a crystal structure, causing it to vibrate or oscillate. The SIT3821AI-2C3-33EE51.200000T oscillator is constructed with quartz crystal, which when connected to an alternating electric current, will vibrate at a distinct frequency. This frequency is pre-determined at the factory with a high accuracy, so it’s input and output should be stable over time.
In order to stabilize the out-put frequency of the SIT3821AI-2C3-33EE51.200000T oscillator, a type of Phase-Locked Loop (PLL) is used. A PLL works by measuring the phase difference between its input signal and its output signal, then uses this information to adjust the current level of the oscillator, so that the output is kept in phase with the input. The PLL ensures that the oscillator operates at its most stable frequency and amplitude over time.
The SIT3821AI-2C3-33EE51.200000T oscillator also has output drive capabilities, allowing the output signal to drive several voltage levels. The output can be amplitude and frequency-leveled, as well as combined with a duty cycle adjustment feature. Additionally, the oscillator provides monitoring features, including output voltage and current monitoring, temperature compensation, and the ability to detect output frequency and amplitude levels.
Overall, the SIT3821AI-2C3-33EE51.200000T oscillator is capable of providing quality and stable output frequency, especially for applications related to cellular communication, such as 5G. The PLL keeps the oscillator operating at its most stable frequency and amplitude over time, while the output drive capabilities and monitoring features provide the necessary flexibility for a variety of applications.
