Oscillators

Oscillators are circuits or components used to create and maintain an oscillating signal. An oscillator can be used to generate a signal that is modulated with information or modulated with data. The signal can be used for communication or it can be used to create a sound. Oscillators are available in several types, and the type used for a particular application depends on the application of the signal. The most common types of oscillators are linear, digital, crystal and phase-locked.

One of the most common types of oscillators is the linear oscillator. It is comprised of two capacitors, one on either side of the oscillator, that are connected in series, along with a common resistor. The capacitor on one side stores charge, while the other capacitor discharges its charge, creating an alternating current within the oscillator. This alternating current is referred to as the oscillation, and this oscillation is the basis of a linear oscillator. Aliasing and its related radio frequency interference can be reduced by implementing various filters within the linear oscillator

Another type of oscillator is the digital oscillator which uses digital logic circuits to produce an electrical signal. These signals can be used for various applications including communication devices and audio production. Digital oscillators are usually used in applications where frequency accuracy or timing stability are important, and they can be programmed to generate signals within a certain range. Digital oscillators are usually implemented with Field Programmable Gate Array (FPGA), Digital Signal Processor (DSP) or Microcontroller (MCU).

Crystal oscillators are used in a wide range of applications, including communications, entertainment systems, navigation, healthcare, and more. A crystal oscillator consists of a quartz crystal, usually in the shape of a rectangle, that is connected to a circuit board that creates and maintains an oscillation signal. The quartz crystal vibrates at a specific frequency and produces an electrical signal that is modulated with a specific frequency and used for various applications. Crystal oscillators provide high accuracy and stability over a wide temperature range, making them suitable for critical applications.

A phase-locked loop (PLL) oscillator is a device that is used for synchronization of two or more signals to the same frequency. PLLs are usually used in communication systems, where the PLL synchronizes the signals of several receivers and transmitters. A PLL oscillator consists of a voltage-controlled oscillator (VCO), a phase detector (PD), a low-pass filter (LPF) and a reference oscillator. The voltage-controlled oscillator (VCO) is the main component of the PLL and it produces an oscillation signal that is used to synchronize the signals across the receivers and transmitters. The phase detector (PD) compares the reference oscillator signal with the output of the voltage-controlled oscillator (VCO) and adjusts the frequency of the VCO according to the difference between the two signals. The low-pass filter (LPF) is used to reduce noise and prevents an unwanted signal from disrupting the synchronization.

The AX7DCF1-986.0000C Oscillator is a phase-locked loop oscillator designed for use in communication applications such as radio frequency identification (RFID) systems and other high-frequency applications.
