Oscillators are often used in signal generations and frequency control of electronic circuits. As an oscillator, CB3LV-5I-14M3180 is utilized in a wealth of applications. Below is an overview of its field of operation and working principle.

CB3LV-5I-14M3180 Application Field

CB3LV-5I-14M3180 is an Oscillator of the voltage-controlled, quartz crystal type. Frequency range for this oscillator is from 10MHz to 80MHz while the nominal frequency is 14.318MHz. If the control voltage is changed from 1Vpp to 5Vpp, frequency could be varied within ±7.5% peak-to-peak against the nominal frequency, while the stability is better than ±3ppm in a given supply voltage and temperature range.

This type of oscillator is extensively adopted in numerous operation scenarios, including, but not limited to, digital communication, DC to DC converter, cell phone, low power SRAM and general xDSL applications. In addition to this, it could be employed for consumer electronics, television, computer and other industrial control systems.

CB3LV-5I-14M3180 Working Principle

Oscillations within an oscillator takes place via a crystal which then engenders a certain number of cycles per second, representing specific frequency. The CB3LV-5I-14M3180 yields a stable signal of 14.318MHz which makes it ideal for frequency-controlled applications. This is done through a quartz crystal resonator with an embedded voltage controlled oscillator circuit, consisting of an amplifier, an oscillator and a feedback loop.

When the input DC voltage is provided, it is partly transformed into an alternating current (known as AC) which then moves to the amplifier. The amplifier increases the amplitude of oscillations and sends it to the quartz crystal. The crystal sporadically vibrates at 14.318MHz and the electric field generates a corresponding voltage with the same frequency of the input. Further, this voltage is directed to the amplifier in an oscillating loop.

The operation process of the voltage-controlled crystal oscillators includes two main stages – quartz crystal resonance and electromagnetic field. Firstly, the natural frequency of the crystal is adjusted in response to the control voltage. Secondly, the alternate current produces an electromagnetic field which is then transformed to an electric field when receiving signals. In this way, the frequency remains 14.318MHz, constantly inducing an electric field with same frequency.

Conclusion

CB3LV-5I-14M3180 is an oscillator of the voltage-controlled, quartz crystal type which finds widespread use in digital communication, DC to DC converter, cell phone, and other similar applications. Its working principle involves a quartz crystal resonator and voltage controlled amplifier which further translates the alternating current to electric field with a constant frequency of 14.318MHz. By understanding the application field and working principle of this oscillator, users are able to choose the right one for their requirements.
