Oscillators

A quartz oscillator is a electronic device used to provide an extremely precise frequency reference for a range of different applications. The most common type of quartz oscillator is called the BB-155.520MBE-T. It is a temperature compensated quartz oscillator (TCXO), meaning it has been specifically designed for long-term stability and temperature accuracy. In this article, we will discuss the application field and working principle of this oscillator.The BB-155.520MBE-T oscillator is designed for a wide range of applications, such as mobile device timing, instrumentation, precision clocks, broadcast transmitters, and others. It is used to generate a stable reference signal with a wide range of frequency options, ranging from 2 MHz to 52 MHz. This provides the flexibility to create a variety of specific timing signals with precision accuracy.The working principle of the BB-155.520MBE-T oscillator is pretty straightforward. Inside the oscillator, there is a quartz crystal that vibrates at a particular frequency. The frequency of this vibration is determined by the shape of the crystal as well as the control voltage applied to it. The frequency is determined by an integrated circuit (IC) which is designed to read the vibration of the crystal and output a signal at the desired frequency.The BB-155.520MBE-T oscillator is an ideal choice for applications requiring precision timing due to its temperature compensation feature. This feature ensures that the oscillator maintains a consistent frequency across a wide range of temperatures. This is achieved with the use of a specialized thermistor which is placed near the quartz crystal. As the temperature changes, the thermistor will adjust the control voltage to ensure the crystal vibrates at the same frequency, regardless of the temperature.As described above, the BB-155.520MBE-T oscillator is an ideal choice for applications requiring a reliable and accurate frequency reference. Its temperature compensation feature ensures a precise frequency reference, even in a wide range of temperatures. This makes it an ideal choice for applications such as mobile device timing, broadcast transmitters, and precision clocks.
