Oscillators

Oscillators are one of the basic building blocks of electronic circuits. An oscillator can either generate an AC waveform, called an “oscillator”, or an AC waveform of specific frequency, called a “tuned oscillator”. The main application field of an oscillator is to generate electrical signals, which can then be used in various applications such as radios, televisions, etc. The type of oscillator required for a particular application is determined by its frequency, amplitude, and waveform characteristics.

XLP735148.500000X application field and working principle

The XLP735148.500000X is a fixed frequency oscillator with a clock frequency of 148.500MHz and a low power consumption of 6mA. It is mainly used for digital circuits, such as microprocessors, and data transmission systems. The output from the oscillator is used to provide the timing needed by the processor or other digital components.

The circuit is built up of a tuning coil, two resistors, two capacitors, two transistors as well as a quartz crystal, as illustrated in Figure 1.

The quartz crystal and coil are connected in series and form the resonator. The frequency is determined by the RC components resistors and capacitors connected to the emitters of the transistors. The output is taken from the collector of the transistors. The capacitors are connected to the resonator to provide AC coupling required by the transistors. It is the combination of the quartz crystal and the RC components that determine the frequency.

When the collector is positive, the transistors become conducting and the voltage across the quartz crystal increases. This causes the inductance to increase, which further increases the current. This positive feedback loop generates an oscillation and creates the output waveform. At the same time, the RC components determine the frequency of the oscillation.

The frequency is kept constant by the quartz crystal, while the amplitude is controlled by the resistor connected to the first transistor. The resistor can be adjusted to set the amplitude to the desired level for the application.

The XLP735148.500000X oscillator has a frequency stability of 0.2ppm and power consumption of 6mA, making it suitable for applications that require low power consumption and high frequency stability.

The XLP735148.500000X is widely used in digital circuits, such as microprocessors and data transmission systems, where its low power consumption and high frequency stability make it an ideal choice.
