Oscillators

SIT5000AC-3E-18E0-12.000000T application field and working principle

An oscillator is a device which generates a repeated signal, usually with a two-state or sinusoidal output. Quartz crystals, MEMS oscillators, RC oscillators and SAW oscillators are all examples of oscillators. SIT5000AC-3E-18E0-12.000000T is one type of high-performance, low-power small size temperature compensated crystal oscillators (TCXOs) which is widely used in many electronic devices due to its excellent performance and long-term stability.

Application Field

SIT5000AC-3E-18E0-12.000000T is mainly used in military radio communications, mobile communication base stations, satellites, aerospace, clocks, networks and other communication related fields. Its application also includes server, router, base station, wireless communication positioning system, laptop computers, tablet PCs, navigational devices, medical equipments and so on.

Working Principle

SIT5000AC-3E-18E0-12.000000T TCXOs are made of different components, including a quartz crystal, temperature compensation circuitry and an oscillator circuit. The working principle of SIT5000AC-3E-18E0-12.000000T is to incorporate temperature compensation circuitry that would help in keeping the output frequency of the device stable, no matter what the temperature of the environment. The quartz crystal is then used to generate a signal at the required frequency.

By using the principle of piezoelectricity, the quartz crystal is made to vibrate at a specified frequency when a voltage of certain level is applied across it. The vibrational frequency is determined by the size of the crystal, and is known as its resonant frequency. The piezoelectric effect causes current to flow across the quartz crystal, when a physical force is applied, producing a voltage which can be used to drive other parts of the oscillator circuit.

The temperature compensation circuitry measures the ambient temperature and adjusts the oscillator\'s frequency accordingly, so that its output frequency remains constant. This helps the oscillator to maintain its degree of accuracy, even if the environment that it\'s operating in changes.
