Working Principle of ASTXR-12-26.000MHZ-511741

The ASTXR-12-26.000MHZ-511741 is a crystal-based oscillator that utilizes the properties of a quartz crystal to generate a highly stable output frequency. Quartz is a piezoelectric material, which means that it can convert a voltage to a mechanical strain, and conversely, a mechanical strain can convert to a voltage. It is this property that is utilized in the ASTXR-12-26.000MHZ-511741 oscillator.Inside the oscillator, a quartz crystal resonator is connected to a circuit containing a feedback loop. When a voltage is applied to the crystal resonator, it starts to vibrate and causes the oscillation of the oscillator circuit. This oscillation produces an output frequency that depends on the mechanical vibration frequencies of the crystal. The ASTXR-12-26.000MHZ-511741 oscillator has a frequency stability of ±50 parts per million over a temperature range of -15°C to +85°C. The oscillator also features an on-chip built-in amplifier, which provides amplification and frequency stability to the oscillation. The amplifier also allows for fine tuning of the output frequency by adjusting the supply voltage.

Conclusion

The ASTXR-12-26.000MHZ-511741 is a quartz crystal oscillator that is used in many electronic applications requiring low-noise and highly stable oscillations in the 20 to 30 MHz range. Its frequency stability is ±50 parts per million over a temperature range of -15°C to +85°C. The oscillator also features an on-chip built-in amplifier, which allows for fine-tuning of the output frequency.
