Oscillators

Oscillators are widely used in many electronic applications, ranging from simple tone generators to complex radar systems. Oscillators have various types which include the crystal oscillator, resistor-capacitor oscillator, voltage controlled oscillator and so on. In this article, we will focus on the 531BC192M000DGR oscillator and its application field and working principle.

Application Field

The 531BC192M000DGR oscillator is recognized as a general-purpose oscillator, designed to cover both high-frequency (HF) and very high-frequency (VHF) applications. This oscillator can generate frequencies from 210kHz to 250MHz, making it suitable for a wide range of applications. It provides an excellent frequency control of better than 1ppm over the -67 to +77°C temperature range. Therefore, the oscillator is ideal for cellular base stations, navigational systems, digital satellite receivers, GSM/CDMA/UMTS pilot systems and other communication systems that require ultra stable frequency sources.

Working Principle

The 531BC192M000DGR oscillator, like all quartz crystal oscillators, uses a quartz crystal as the frequency-determining element. The crystal has a natural resonant frequency determined by its size, shape and other properties. The crystal is connected to two parallel tuned circuits, one tuned circuit being connected to signal ground and the other being connected to the output port. The tuned circuits are basically LC circuits (L representing inductors and C representing capacitors).

When an alternating current (AC) signal is applied to the tuned circuits, the crystal starts to vibrate. This causes the frequency of the oscillator to “lock” to the natural resonant frequency of the crystal. The frequency of the signal is determined by the crystal and the LC circuit and the types of components used determine the stability of the oscillator. The LC circuit provides the necessary feedback to the crystal to keep the frequency locked and the output stable.

Conclusion

In conclusion, the 531BC192M000DGR oscillator is a general-purpose oscillator that can generate frequencies from 210kHz to 250MHz. It provides excellent frequency stability over a wide temperature range. The oscillator works by using a quartz crystal combined with two LC circuits to create an oscillating signal with a stable frequency. The 531BC192M000DGR oscillator is suitable for many different applications, making it a popular choice for many designers.
