Ceramic Resonator Clock Circuit

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.

Ceramic resonator clock circuit.

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. Crystal is the common term used in electronics for the frequency determining component a wafer of quartz crystal or ceramic with electrodes connected to it. The operating principle of these oscillation circuits can be seen in fig 2 1. Also what kind of osciallator circuits.

You can also replace the 10 7 mhz ceramic resonator with any other between 2 3 mhz to 26 mhz range. The lower q and higher frequency range achievable can be beneficial in use of tcxos temperature compensated crystal oscillators. Crystal and ceramic resonator based oscillators are most often implemented as pierce oscillators in which the crystal or resonator serves as a tuned element in the feedback of an inverting amplifier. They do not hold their frequency as well.

This may not be important for a microprocessor but will be important if the circuit is used in a radio a clock or other timing critical applications. 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. The operating principle of these oscillation circuits can be seen in fig 2 1. Resonators are made from ceramic elements rather than quartz.

The design of the circuit varies with the application and the ic to be used etc. The most commonly used circuit is the colpitts circuit. They cost less and so are used where stability isn t as important. 5 discount for the first 40 to order on jlcpcb with code jlcpcbnoob learn how crystal and ceramic resonators work.

For stable operation in such a design the phase shift compensation and gain control are provided by additional capacitors and resistors. A ceramic resonator is often used in place of quartz crystals as a reference clock or signal generator in electronic circuitry due to its low cost and smaller size. 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. Although the basic configuration of the circuit is the same as that of a crystal controlled oscillator the difference in mechanical q results from a difference in circuit constants.

Power up the circuit with a clean 3 v to 5 v dc supply i e with a single li ion battery is. The most commonly used circuit is the colpitts circuit.
