OscillatorsOscillators are electronic components consisting of a frequency generator and a frequency divider. They play an important role in maintaining the speed and accuracy of various electronic devices and systems. The AST3TQ53-T-20.000MHZ-1-SW-T5 oscillator is a high-speed, low-power, precision-stability device designed to generate precise and stable frequencies within a wide range of controller applications.This oscillator uses a two-stage PLL circuit to generate frequencies from 20.000 MHz to 20.256 MHz and apply frequency correction over the -20°C to +80°C temperature range. It typically features a high-performance temperature compensated RC oscillator (TCXO) module and provides a highly stable reference signal with accuracies up to ±2.5ppm at one year aging. The oscillator also comes with a user-configurable frequency divider that can divide the output frequency by any number from 1 to 15. The AST3TQ53-T-20.000MHZ-1-SW-T5 oscillator is designed to provide high accuracy in the industrial sector, where accurate frequency control is essential, but difficult to obtain. It is also used in communication systems, navigation systems, radar systems, military and aerospace systems, automotive systems, consumer electronics, and many other applications. The frequency stability and accuracy of this oscillator make it a valuable tool for a variety of applications where precision timing and frequency accuracy is needed.In terms of working principles, this oscillator works by using a phase-locked loop (PLL) circuit to precisely generate frequencies from 20.000 MHz to 20.256 MHz. This oscillator has two main components: the frequency generator and the frequency divider. The frequency generator converts an input frequency into an output frequency by using a delay line, a voltage-controlled oscillator, or a combination of the two. The frequency divider is an electronic circuit that divides the output frequency by a constant. The frequency divider is responsible for downconverting the reference frequency to a frequency that is selected by the user, which can be any number from 1 to 15.The AST3TQ53-T-20.000MHZ-1-SW-T5 oscillator is designed to provide improved accuracy and better temperature compensation thanks to its high-performance TCXO. The combination of the TCXO and precision frequency divider allows this oscillator to provide high stability and accuracy for precision timing applications. With its high accuracy and stability, this oscillator is ideal for applications that require precise and stable frequencies in order to maintain the speed and accuracy of the device or system.
