AX7PBF4-122.8800T

Oscillators are special circuits that are designed to oscillate at a predetermined frequency. An example of this is the AX7PBF4-122.8800T oscillator. It provides an output frequency of 122.8800 MHz and is typically used in radio, communications, automotive, or instrumentation applications.

Principle of Operation

The AX7PBF4-122.8800T oscillator operates by having its crystal connected to an inverting amplifier, whose output is connected to the inverting input of the amplifier. A feedback loop is formed by connecting the output of the inverting amplifier back to its input, using a resistor divider. This creates a negative feedback loop and causes the amplifier to oscillate at a specific frequency, determined by the characteristics of the crystal.

The oscillation frequency of the AX7PBF4-122.8800T is determined by the frequency response characteristics of the crystal. This is a highly stable and accurate frequency, since it is more resistant to changes in temperature and external noise than other oscillators.
