ASTX-H12-19.200MHZ-I25-T Application Field and Working Principle

Oscillators are electronic circuit components widely used in many applications for generating an electrical signal with periodic oscillations. One of such oscillators is theASTX-H12-19.200MHZ-I25-T,which consists of a miniature quartz oscillator packaged in a hermetically sealed metal can, designed for use in commercial AC operated equipment.The frequency accuracy of this oscillator is ±50 ppm or better in the temperature range of 0 to 50°C, and the supply voltage range is 5 to 12 V with operating current at around 25 mA.

The typical application fields of the ASTX-H12-19.200MHZ-I25-T oscillator involve data communications, radar for navigation and tracking, personal computers, instrumentation systems and other digital equipment. Owing to its compact size and low power consumption, this device has great potential for use where limited space and power are necessary.

The ASTX-H12-19.200MHZ-I25-T works based on the principle of oscillation. An oscillator is a circuit that generates an alternating current signal, in which part of the output current is returned to the input of the circuit, and the other part is outputted from the circuit as a periodic signal. Usually this returned current is out of phase with the input signal; when the two signals meet, their amplitudes reinforce each other, producing a positive feedback, and an oscillating current then persists in the circuit.

Most oscillators are based on the generation of sinusoidal waveforms by using electronic circuits. The ASTX-H12-19.200MHZ-I25-T oscillator uses quartz crystal as the resonator to convert electrical oscillations into mechanical vibrations and vice versa, thus producing a sinusoidal wave form at a precisely determined frequency. The quartz crystal is vibrated at a certain frequency determined by its physical characteristics, and the electrical signal necessary to superimpose this vibration on the crystal is provided from the integrated circuit.

In conclusion, the ASTX-H12-19.200MHZ-I25-T oscillator is a miniature quartz oscillator with specified frequency accuracy, ideal for use in many applications needing limited space and power. Its working principle is based on the principle of oscillation, in which part of the output current is out of phase with the input signal, producing a positive feedback. In order to generate a precise frequency, the oscillator uses quartz crystal as the resonator.
