Oscillators are electronic components that produce a repetitive pulse or waveform. The CB3LV-3I-20M4800 is a particular type of oscillator known as a voltage-controlled oscillator (VCO), which can be used to produce frequency control and modulation in many applications. In this article, we will explore the application field and working principle of the CB3LV-3I-20M4800.

Application Field

The CB3LV-3I-20M4800 is a voltage-controlled oscillator that is used primarily in frequency synthesizers and other frequency modulation control applications. It is typically used to generate variation of the carrier frequency, such as the control of radio communication systems and as a frequency shift key modulation (FSK) for data transmission. It can also be used in frequency modulation (FM) or phase modulation (PM) applications as well as for audio frequency modulation (AFM) or high-speed digital communications systems. Other applications for the CB3LV-3I-20M4800 include digital signal processing as well as frequency stabilization for communications audio and video equipment.

Working Principle

The CB3LV-3I-20M4800 is an integrated circuit (IC) voltage-controlled oscillator that uses an externally applied voltage to control the frequency of the output waveform. It consists of two main components: a high-quality linear amplifier and a voltage-to-frequency converter. The linear amplifier is used to amplify the signal, while the voltage-to-frequency converter is used to convert the amplified signal into a square wave with a specific frequency. The frequency of the output waveform is directly proportional to the voltage supplied to the IC.

The oscillation frequency of the CB3LV-3I-20M4800 is determined by the applied voltage, which is typically 0-5V. The output frequency is linearly proportional to the applied voltage, and the relation between the applied voltage and the frequency can be adjusted by the external components connected to its input pins. By changing the external components, the user can adjust the frequency range of the oscillator.

The total operating range of the CB3LV-3I-20M4800 is from 1Hz to 20MHz. The frequency stability is typically ±2.5 ppm over the temperature range of -20℃ to +70℃. The circuit is enclosed in a small 2 x 2mm package, making it ideally suited for applications where space is limited.
