Oscillators: 7Q-19.2 0 MDG-T Application Field and Working Principle

Oscillators are fundamental circuits used in electronic and electrical devices. Applications of oscillators range from controlling clocks of computers to triggering electrical relays and regulating frequency or time intervals in many systems. The 7Q-19.2 0 MDG-T is a type of oscillator typically used for high stability and high accuracy performance applications. This article will discuss the application field and working principle of the 7Q-19.2 0 MDG-T oscillator.

Application Field

The 7Q-19.2 0 MDG-T oscillator is an ideal solution for applications that require extremely precise and reliable frequency control, such as frequency-controlled timing, as well as systems that retain time accuracy and stability across a wide range of temperatures and environmental conditions. Such applications include precision frequency control of cellular networks, GPS timing, satellite navigation, military and aerospace systems, and medical and laboratory instrumentation.

The 7Q-19.2 0 MDG-T oscillator has also been used in high-precision, ultra-low-voltage, low-power, 7-day circuitry. With its high output accuracy performance, it is suitable for any system that requires a precision frequency control in the range of 5 kHz to 9 MHz, such as smart meters, smart grids, environmental monitoring, and industrial process control systems.

Working Principle

The working of the 7Q-19.2 0 MDG-T oscillator is based on its active nodes, which includes a varactor diode, a quartz crystal, and an inductor. The varactor acts as a variable reactance to the oscillator\'s oscillating circuit, while the quartz crystal is a dual-emphasis electrically tuned filter that operates in a frequency-dependent manner, providing precise frequency control. The inductor acts as a filter to the oscillator, suppressing undesirable noise.

When the 7Q-19.2 0 MDG-T oscillator is connected to an external power supply, the inductor stores energy as its current increases. The current passes through the quartz crystal, whose impedance changes with frequency, thus allowing the oscillator to self-regulate the frequency and maintain oscillation. As current flows through the varactor diode, its capacitance increases, further regulating the frequency of the oscillator. The oscillating frequency is thus determined by the combination of components and their values.

Conclusion

The 7Q-19.2 0 MDG-T oscillator is a popular choice for applications that require precise frequency control for timing, as well as systems that require accuracy and stability even when subjected to varying temperatures and environments. Its working is based on the combination of a varactor diode, a quartz crystal and a inductor, which together allow the oscillator to regulate its frequency and maintain oscillation.
