OSTX-H12-5.000MHZ-I25-T Application Field and Working Principle

Oscillators are special components that generate alternating electric current or voltage. They are widely used in electronic systems where sine wave signals with uniform frequency and amplitude are needed. The ASTX-H12-5.000MHZ-I25-T is an oscillator specifically designed for precision timing applications. This article examines the application fields and working principle of the ASTX-H12-5.000MHZ-I25-T.

Application Fields

The ASTX-H12-5.000MHZ-I25-T is designed for use in precision timing applications. It is mainly used as a clock generator for high-speed digital circuits such as microprocessors and memory chips. The oscillator can provide accurate timing for devices such as peripheral components, memories, and logic circuits. It also provides reliable clock signals for analog-to-digital converters and other data-acquisition devices.

Working Principle

The ASTX-H12-5.000MHZ-I25-T is a hermetically sealed, precision oscillator. It consists of a quartz crystal mounted in an enclosure with metal electrodes and ceramic caps. The quartz crystal is driven by an external signal current. This creates a vibration in the crystal, allowing a steady frequency to be generated. The frequency is then divided down by a series of dividers resulting in a precise signal. The signal is then output from the oscillator.The oscillator is designed for long-term stability. It has an accuracy of +/- 0.0005pH+/-50 parts per million (ppb), which is about five times better than the typical Freon oscillator. The oscillator can operate over a temperature range of -20 to +70 degrees Celsius and is protected from environmental effects such as shock and vibration.

Conclusion

The ASTX-H12-5.000MHZ-I25-T is an oscillator specifically designed for precision timing applications. It has an accuracy of +/- 0.0005pH+/-50ppb, and operates over a temperature range of -20 to +70 degrees Celsius. The oscillator works by generating a steady frequency from a quartz crystal that is driven by an external signal current. The signal is then divided down by a series of dividers resulting in a precise output signal. The oscillator is mainly used as a clock generator for high-speed digital circuits such as microprocessors and memory chips.
