What are Oscillators?

Oscillators are electronic components used to generate a repeating waveform. They are a type of circuit that produces an oscillating voltage with a certain frequency and magnitude. Oscillators are used in a variety of electronic applications, such as radios, television, and computers.

AST3TQ53-T-12.800MHZ-5-C Oscillator

The AST3TQ53-T-12.800MHZ-5-C is an oscillator used for producing a 12.800 MHZ waveform. It is a miniature, surface mount, 3 pin oscillator with a frequency of 12.800 MHz, rise time of a maximum of 5 ns, and a precise timing accuracy of 20 ppm. The unit also operates at a supply voltage of 3.3-5.5 VDC, with an operating temperature range of -40 to +85 degrees Celsius.

Application Field

The AST3TQ53-T-12.800MHZ-5-C oscillator is a highly precise and reliable oscillator suitable for a wide range of electronic applications. It is most commonly used in high-performance digital communication applications, such as digital cellular systems, satellite navigation systems, and VHF/UHF and broadband systems. The small size and low power consumption of the oscillator make it suitable for portable devices as well.

Working Principle

The AST3TQ53-T-12.800MHZ-5-C oscillator produces a precise 12.800 MHZ periodic signal. It works by using an electrically pulsed oscillator circuit to generate a sine wave at the desired frequency. This sine wave is then sent through a Feedback loop and compared to a reference frequency. Any difference between the original wave and the reference frequency is then adjusted, thus ensuring the accuracy of the output wave. The output is then amplified and cleaned up using filters to obtain the desired waveform.
