It is also used in industrial automation applications and large-scale power plants and chemical processing plants. Furthermore, it is used in telecommunication equipment, government and public institutions, and research laboratories.

Working Principle

The 590BB148M350DGR is an oven controlled oscillator (OCXO) built from quartz crystal and designed to generate a very stable frequency within the range of 3.2MHz to 100MHz. The quartz crystal is enclosed in a temperature-controlled chamber, commonly referred to as an oven. The oven continually monitors and maintains the crystal’s temperature. This creates an environment which is independent of outside temperature changes and minimizes temperature related errors and ensures a highly stable frequency.

The 590BB148M350DGR works by combining an oscillator circuit and quartz crystal. This combination creates a circuit called an “oscillation loop”, which is a tuned closed-loop circuit. The crystal acts as a frequency standard and is tuned to a specific frequency by the oscillator circuit. When a voltage is first applied to the circuit, the crystal starts vibrating at its resonant frequency, caused by the oscillator circuitry.

The crystal and oscillator are also designed for high stability and accuracy. The crystal must be carefully designed and manufactured with precision or else if any defects occur, they will affect the performance of the oscillator and cause instability or errors in the crystal. To reduce imperfections, the crystal undergoes a series of tests to ensure accuracy. To ensure long-term stability, the OCXO is built with a negative temperature coefficient. This means that when the temperature of the crystal changes, the frequency of the oscillator will also adjust accordingly.

Conclusion

The 590BB148M350DGR oscillator has many advantages in industrial applications, with excellent stability, acceleration performance, environmental robustness, low power consumption and compact size. Its rugged construction and high reliability makes it ideal for many different industrial applications. Moreover, it is designed with a negative temperature coefficient to guarantee long-term stability and excellent accuracy.
