Oscillators are electrical circuits, which generate electric signals with a specified frequency, amplitude and phase. CE3390-20.480 oscillator is one of these oscillators and is used in applications such as variable frequency drives, adjustable speed drives, frequency synthesisers, voice communication systems and data transmission over long distances.The CE3390-20.480 oscillator features a built-in PLL which can be programmed and locked to a crystal frequency, providing better frequency accuracy and stability. It has a high frequency stability of ±0.022 PPM and a wide operating temperature range of -40°C to +90°C. The oscillator also features a low supply voltage (3.3V to 5.5V), low start-up current (3mA max.), low current consumption (10mA max.), and a low power dissipation (0.8W max.). It is a low cost, reliable and highly accurate oscillator.The working principle of CE3390-20.480 oscillator is based on the voltage-controlled oscillator (VCO) which is a type of oscillator circuit that is used to generate a controlled frequency with high precision and stability. The VCO consists of an amplifier which is connected to a feedback loop. The output of the amplifier is fed back to the input and is compared with a reference voltage. The gain of the amplifier is adjusted in such a way that the reference voltage is maintained at the desired level. When the input signal level is varied, the gain of the amplifier is also adjusted, thus creating a change in the output frequency of the oscillator.In the case of CE3390-20.480, the oscillator uses a phase locked loop (PLL) to achieve both frequency accuracy and stability. The PLL consists of a reference frequency oscillator, a phase detector, an amplifier and a VCO. The reference oscillator produces a reference frequency signal, which is compared with the frequency generated by the VCO. If there is a difference between them, it will be detected by the phase detector, amplified and then fed back to the VCO, thereby synchronizing the VCO with the reference signal. This feedback loop is constantly adjusted and stabilizes the output frequency of the VCO.The CE3390-20.480 oscillator can also be programmed through an external display/controller such as a PC or a smartphone application. Through these external devices, the user can adjust the frequency, amplitude, and phase of the output signal. The programming can also be done without external devices by using the built-in programming pins of the oscillator. The CE3390-20.480 oscillator is highly reliable and can withstand harsh environmental conditions and temperature variations, making it ideal for industrial applications. It is also cost-effective, low power consuming and highly accurate, making it suitable for various applications, such as variable frequency drives, adjustable speed drives, frequency synthesisers, voice communication systems and data transmission over long distances.
