Ceramic Resonator Clock Circuit

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.

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. 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. That s all you need to make this shortwave transmitter circuit. 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.

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. 5 discount for the first 40 to order on jlcpcb with code jlcpcbnoob learn how crystal and ceramic resonators work. Also what kind of osciallator circuits. The operating principle of these oscillation circuits can be seen in fig 2 1.

The lower q and higher frequency range achievable can be beneficial in use of tcxos temperature compensated crystal oscillators. A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric resonator a crystal as its frequency determining element. Resonators are made from ceramic elements rather than quartz. They cost less and so are used where stability isn t as important.

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. The most common oscillator circuit for a ceramic resonator is a colpitts circuit. The operating principle of these oscillation circuits can be seen in fig 2 1. The most commonly used circuit is the colpitts circuit.

You can also replace the 10 7 mhz ceramic resonator with any other between 2 3 mhz to 26 mhz range. The most commonly used circuit is the colpitts 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. 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.

For stable operation in such a design the phase shift compensation and gain control are provided by additional capacitors and resistors. The design of the circuit varies with the application and the ic to be used etc.
