Voltage Controlled Oscillators (VCOs), also known as Voltage Tunable Oscillators (VTOs), are versatile and efficient components in many different applications. They are used to generate and provide an output signal which is a function of a wide variety of input signals. This is accomplished through the use of a voltage-sensitive circuit, usually a varactor (a semiconductor diode) or other type of semiconductor switch. The CVCO55BE-3100-3350 is one such voltage-controlled oscillator.

The CVCO55BE-3100-3350 has a range of 1800-3200 MHz with a tuning range of 2-800 MHz; it is also rated for an operating temperature range of -40°C to 85°C. The minimum phase noise is -90 dBc/Hz at 100 KHz offset, making it ideal for systems where precise timing is critical, such as satellite systems and cellular networks. It is packaged in a compact 5.0 x 5.0 mm QFN surface-mount package and requires a single +3V supply. The frequency can be adjusted via an external voltage control pin, allowing for remote tuning over a wide frequency range, while the built-in temperature compensation ensures stable operation over the operating temperature range.

The working principle of the CVCO55BE-3100-3350 is based on a voltage to frequency relationship, driven by an external control voltage. The input, applied to the oscillator’s control pin, is then compared to an internal voltage, typically from a bandgap reference. A differential amplifier, named the phase-frequency detector, converts this difference into a current. This current is then fed into an integrator, which generates a voltage and causes the oscillator to oscillate. The tuning range and frequency range is determined by the capacitance of the varactor diode, which is determined by the applied control voltage. The wider the range of voltages applied, the wider the tuning range and frequency range of the oscillator.

The CVCO55BE-3100-3350 is typically used in many different applications, including mobile communication and computer systems, aviation and navigation, radio communication, and instrumentation and process control systems. Due to its wide tuning range and low phase noise, the CVCO55BE-3100-3350 can be used in a variety of different applications, from satellite systems to cellular and local area networks, as well as a wide range of consumer electronics products. Its ability to operate in extreme temperatures, along with its highly reliable output, make it an ideal choice for many different applications.
