Ceramic Resonator Oscillator

Similar to the crystal oscillator ceramic resonator is also an electronic circuit or a device used to generate an output of oscillation frequency with the help of ceramic as a resonating piezoelectric material.

Ceramic resonator oscillator. The material can have two or more electrode which when connected to an oscillator circuit gets mechanical vibration as a result an oscillating signal of a specific frequency is generated. When connected in an electronic oscillator circuit resonant mechanical vibrations in the device generate an oscillating signal of a specific frequency. In terms of application ceramic resonators are used in microprocessors where their frequency stability is not important and crystal oscillators are used for more precise time based applications. Ceralock find a broad range of applications such as automotive electronics communications personal computing and medical healthcare equipment.

Ceramic resonators ceralock are made of high stability piezoelectric ceramics that function as a mechanical resonator. Another oscillating circuit is the one that use resonators. In a ceramic resonator oscillator the inductor is replaced by a ceramic resonator taking advantage of the fact that the resonator becomes inductive between resonant and anti resonant frequencies. A ceramic resonator is sometimes referred to a dielectic resonator they are commonly used for timing devices which create a clock signal.

A ceramic resonator works similar to a crystal. The most commonly used circuit is the colpitts circuit. The ceramic resonator utilizes a frequency within the electrical component but unlike the crystal which has a frequency tolerance of 10 30 ppm a ceramic resonator carries a 0 5 or 5 000 ppm frequency tolerance which is generally used in microprocessor applications where absolute stability is not important. What is a ceramic resonator.

What is a ceramic resonator. The operating principle of these oscillation circuits can be seen in fig 2 1. The active part which makes the oscillator work is an amplifier which supplies the energy to keep the oscillation going. The operating principle of these oscillation circuits can be seen in fig.

Before we look at the ceramic and crystal resonators let s take a look at the lc oscillator so we need a coil and capacitor. Like the similar quartz crystal they are used in oscillators for purposes such as generating the clock signal used to control timing in computers and other digital logic devices or generating the. The resonator or crystal itself has two connections. Like you say the oscillator needs extra components the two capacitors.

On the left the crystal right the ceramic resonator. See that tutorial for more information. Remember from the inductance meter tutorial that an lc tank will resonate at its natural frequency. This type of signal oscillates between a high and low state using a piece of piezoelectric ceramic connected to two or more electrodes.

A ceramic resonator is an electronic component consisting of a piece of a piezoelectric ceramic material with two or more metal electrodes attached.
