Resonators[trade_no] are critical to the performance of oscillators [trade_no]and filters[trade_no]. Common resonator types include transmission line resonators, coaxial resonators, dielectric resonators, crystal resonators[trade_no], ceramic resonators[trade_no], surface acoustic wave (SAW) resonators, bulk acoustic wave (BAW) resonators, and yttrium iron garnet (YIG) resonators. Due to the frequency generated by the resonator, it has the characteristics of stability and good anti-interference performance, and is widely used in various electronic products. The frequency accuracy of quartz crystal resonator is higher than that of ceramic resonator, but the cost is also higher than that of ceramic resonator.
Oscillator is a kind of energy conversion device, which converts DC electric energy into AC energy with a certain frequency. Its circuit is called oscillation circuit. Oscillators can be divided into two types: harmonic oscillators[trade_no] and relaxation oscillators[trade_no].
Oscillator[trade_no] is an electronic component used to generate repeated electronic signals (usually sine wave or square wave). Its circuit is called oscillation circuit. An electronic circuit or device that can convert direct current into alternating current with a certain frequency signal output.
There are many kinds of oscillators, which can be divided into self-excited oscillator and other excited oscillator according to the oscillation excitation mode; According to the circuit structure, it can be divided into resistance capacitance oscillator, inductance capacitance oscillator, crystal oscillator, tuning fork oscillator, etc; According to the output waveform, it can be divided into sine wave, square wave, sawtooth wave and other oscillators. It is widely used in electronic industry, medical treatment, scientific research and so on.
Resonator is an electronic component that produces resonant frequency. It is a typical passive component, which needs peripheral circuits to drive it to work and produce clock output. It includes crystal resonator and ceramic resonator.
Oscillator is a kind of energy conversion device, which converts DC electric energy into AC energy with a certain frequency. Its circuit is called oscillation circuit. Oscillator is an active device, and oscillator has a control circuit more than resonator. Including crystal oscillator and silicon oscillator.
