VCO790-2300T

Voltage Controlled Oscillators (VCOs) are widely used in many applications, ranging from radio communications to frequency synthesis. VCOs are typically used as an oscillator with a frequency output that is proportional to a dc input, thus allowing a user to control the oscillator frequency. One example of this type of oscillator is the VCO790-2300T. This device is used in a variety of applications, and its working principle can be broken down into two basic parts.

Application Field

The VCO790-2300T is focused on applications requiring low input voltage and moderate frequency range. Applications such as frequency synthesis, FM/PM modulation, Bessel decoding/detection, and mobile communications all make use of the device’s versatile architecture. This device is also optimized for loop filter integration, further simplifying the design process.

Due to its ability to operate at low input voltages and moderate frequency ranges, the VCO790-2300T is ideal for systems that require low-power operation. This can be especially beneficial when using mobile devices, as the device helps to reduce overall system power consumption. In addition, it has been designed for use in a variety of system architectures; making it easier for designers to integrate into existing and future systems.

Working Principle

The VCO790-2300T uses a combination of inductance and capacitance to provide a low-power, moderate-frequency signal. The device utilizes a voltage-mode coupling mechanism to achieve its linear frequency-voltage relationship. In this arrangement, a fixed inductance (L1) and capacitance (C1) form an LC oscillator. When a DC voltage is applied across the capacitance, the resulting current varies linearly with the input voltage. This current in turn varies the inductance, in effect varying the oscillation frequency.

The VCO790-2300T also offers the user additional flexibility by way of its programmable output divider. By changing the divider ratio, the output frequency of the VCO can be adjusted accordingly. This can be used to accommodate system architectures with different frequency requirements.

In summary, the VCO790-2300T is a low-power, moderate-frequency voltage-controlled oscillator designed for a variety of applications. It utilizes a voltage-mode coupling mechanism and programmable output divider to achieve its versatility, making it an ideal choice for designers who are looking for a reliable and robust oscillator solution.
