CB3-5I-14M7456 Datasheet/PDFAn oscillator is a device designed to generate an output of a defined frequency. Generally speaking, oscillators maintain the same output frequency periodically over time. The output of an oscillator is generally sinusoidal waveforms likes sine or triangle waveform or rectangular waveforms such as square waveform. Oscillators are useful in many applications like clock or timing synthesis, as an electronic test waveform, frequency synthesizer or for signal conversion and modulation.
CB3-5I-14M7456 is an oscillator designed by OVKO Company, with a operating temperature range from -40 °C to 85 °C. This family of oscillator normally operate in the frequency range from 10MHz to 54MHz and feature a TTL output with a load of <10 pF. They address a wide range of applications, such as radio, telecommunications, radar, electronic warfare, and scientific instrumentation.
This oscillator is based on an internal quartz crystal, so as to achieve a high frequency accuracy and PPM stability. The crystal oscillator consists of an LC oscillator with frequency-selective elements (generally including quartz crystal plates) connected between the circuit output and return. The frequency of such oscillators is determined by the frequency-selective element. When the necessary DC bias voltage is applied to the oscillator and the circuit is driven by a signal, the signal is fed back from the output to the input, the oscillation circuit will produce an oscillation, at the frequency determined by the frequency-selective elements in the circuit.
The clock signal from the CB3-5I-14M7456 oscillator is in the form of square wave signals. The frequency of the output waves varies according to the frequency of the oscillator. For instance, if the oscillation frequencies are 10MHz ， the signal output frequency will be 10MHz.
The circuit of the oscillator produces a particular frequency, when certain conditions (load, temperature, voltage and current) satisfy the oscillation conditions. Different values of these parameters will impact the oscillator\'s performance, and eventually create deviation in the output. This means that the CB3-5I-14M7456 oscillator will have a deviation in time of the output signal, which might lead to a decrease in accuracy and an increase in distortion.
OVKO\'s CB3-5I-14M7456 oscillator offers very good frequency stability, which is mainly determined by the stability of the quartz crystal. The frequency of the state of the quartz crystal is affected by temperature, which in turn will affect the stability of the oscillator\'s operation. In order to guarantee stability of the oscillator, the oscillator board contains temperature sensor and thermal compensator circuit which helps to reduce the changes in the operating frequency caused by the varying temperature.
The oscillator also provides robust isolation against unwanted electrical noise. The electronic environment will generate electrical interference, and the oscillator internal passivation layer is designed to reflect the impact of the interference on the component and help blocking it. Advanced techniques include using materials with high permeability, such as ferrites, which helps reduce the noise generated by the oscillator and improves its output frequency accuracy.
In conclusion, the CB3-5I-14M7456 oscillator is designed to provide an output of a defined frequency. The oscillator can offer a high frequency accuracy and PPM stability with a wide range of frequencies limited from 10MHz to 54MHz. Furthermore, the oscillator features a TTL output with a load of <10pF, and provides robust isolation against unwanted electrical noise. As stated before, this family of oscillator is used for a variety of applications, such as radio, telecommunications, radar, electronic warfare, and scientific instrumentation.
