Voltage Controlled Oscillators (VCOs)

A Voltage Controlled Oscillator (VCO) is a specialized oscillator which is essentially an electronic oscillator whose output frequency is directly proportional to a voltage input. VCOs are typically used for making frequency synthesisers, for communications applications, for control systems and for other electronic applications. The CVCO55CL-0830-0970 is a popular Voltage Controlled Oscillator (VCO) that is often used in the design of communication and control systems.

Application Field

The CVCO55CL-0830-0970 is a versatile Voltage Controlled Oscillator (VCO) that is used primarily in communications, control and other electronic systems. This VCO has a wide operating frequency band (830 – 970 MHz) and a wide tuning voltage range (0.6 – 2.0V) which makes it well suited to a wide range of applications, including Frequency Synthesisers, Radio Transmitting and Receiving Systems and Direct Sequence Spread Spectrums (DSSS) systems.

Working Principle

The CVCO55CL-0830-0970 is a Voltage Controlled Oscillator (VCO) that is a morphable-core device. This means that the VCO can be adjusted with a voltage to change the frequency of its output. The VCO has four separate tuning pins. The tuning pins are the operating frequency, the amplitude, the type of circuit topology, and the temperature compensation, to ensure superior dampening characteristics over a wide operating temperature range.

The CVCO55CL-0830-0970 utilizes a morphable-core fundamental approach to achieve a wide tuning range. The VCO\'s core is initially “set” with a fixed inductance. An external bias voltage is then applied to the four tuning pins of the VCO to adjust its frequency characteristics. For example, when a higher bias voltage is applied, the frequency of the VCO output will increase. The frequency adjustment can be done manually or electronically, depending on the preference of the user.

The CVCO55CL-0830-0970 is a low-power VCO, with a maximum power dissipation of only 35 mW. This makes it suitable for small portable devices, remote transmitter systems, and other location-dependent applications. With an integrated power-down mode, the VCO can also be put into a low-power “stand-by” mode when not in use, further reducing power consumption.

Conclusion

The CVCO55CL-0830-0970 is a Voltage Controlled Oscillator (VCO) that is used mainly in communications, control and other electronic systems. It is a morphable-core device that utilizes four tuning pins to adjust the frequency characteristics. It has a wide operating frequency band (830 – 970 MHz) and a wide tuning voltage range (0.6 – 2.0V). With a low power consumption of only 35 mW and an integrated power-down mode that allows it to enter a low-power “stand-by” mode, the CVCO55CL-0830-0970 is an ideal choice for design of communication and control systems.
