Crystals are used in a variety of applications and are an essential building block of modern electronics. The HC-49/U-S11059200ABJB is an example of a crystal oscillator that is used in a wide range of electronics applications. This article will discuss the application field and working principle of the HC-49/U-S11059200ABJB.

The HC-49/U-S11059200ABJB is a commercial-grade KA crystal oscillator designed to operate between 10MHz and 15MHz. It has a gold-plated package and stabilities of 11ppm over the operating temperature range. Its output waveform is a symmetrical square wave and it operates at a nominal 30pF capacitance.

The HC-49/U-S11059200ABJB is used in many types of electronic applications. It is often used as an oscillator in digital systems such as microprocessors, clocks, watches, and computer systems. It is also widely used in analog circuits as well, in devices such as receivers and transmitters. Other uses include time-sensitive tasks, such as those requiring precision timing, and the synchronization of multiple systems.

The working principle of the HC-49/U-S11059200ABJB crystal oscillator is based on the piezoelectric effect. This effect occurs when a crystal is mechanically stressed, causing it to generate a voltage on its surface. This voltage can be used to create an alternating current, which is what is needed for a crystal oscillator to function.

The crystal in the HC-49/U-S11059200ABJB is connected to two metal electrodes, which act as opposite charges. A current is applied to one electrode, and this causes vibrations to occur in the crystal, resulting in an AC voltage that rises and falls in a predictable, sinusoidal wave. The frequency of this wave is determined by the physical properties of the crystal, such as its size and shape.

The alternating current is then converted into a square wave form by a waveform shaping circuit. The waveform is amplified and then delivered to the circuit that needs it. This waveform is then used to trigger various events in the circuit, such as switching signals, timing sequences, and other tasks.

In conclusion, the HC-49/U-S11059200ABJB is a commercial-grade oscillator used in a variety of electronic applications. It operates using the piezoelectric effect, where a current applied to the crystal causes vibrations which generate a sinusoidal voltage. This voltage is later converted into a square wave form, which is used by circuits to carry out various tasks, such as timing and synchronization.
