Voltage Controlled Oscillators (VCOs) represent a significant building block of many digital systems, and their unique capability of finely tuning frequencies over a wide range makes them invaluable components in applications ranging from communication systems and synthesizers to frequency filters and modulators. The CVCO55BE-2100-2200 is a Pulse Width Modulation (PWM) based VCO designed for use in applications that require precise control of frequency and tuning. This article will focus on the application field and working principles of the CVCO55BE-2100-2200.

The CVCO55BE-2100-2200 is designed to be used in a wide range of applications, such as wireless communications, satellite navigation systems, radar systems, and telecommunication systems. The device is specifically engineered to be compatible with applications that use the direct-conversion transmit/receive architecture and require low distortion, wide tuning range, and high spurious performance. The device is also suitable for use in higher-frequency applications that require stable, low-jitter clock signals, such as digital signal processing (DSP) systems and local oscillator circuits.

As for its working principles, the CVCO55BE-2100-2200 utilizes a Pulse Width Modulation (PWM) technology in order to precisely control its frequency. In this PWM system, the VCO output signal is generated by comparing the input voltage to a triangle wave at a constant frequency. The output signal is then provided to an output divider to set the desired output frequency. The PWM system also allows the device to maintain a narrow loop bandwidth with fast settling, resulting in a low jitter, low phase noise signal.

In addition to the PWM technology, the device is also equipped with a frequency tracking feature that allows the device to “lock” onto a desired output frequency and maintain it by adjusting the voltage across the capacitor of the frequency loop. This tracking feature makes the device extremely stable and reliable for operation in applications that require precise frequency control over a wide temperature range. Furthermore, the device features a wide tuning range of 1.2-2.2 GHz with a tuning resolution of 10 Hz, making it suitable for precise frequency control even in complex (e.g., telecommunication) systems.

Finally, the CVCO55BE-2100-2200 also features a low spurious performance, allowing the device to reject spurious noise and spurious signals, making it suitable for applications where noise and interference can have a significant impact on system performance. The device also features an extremely low RMS phase noise of -94 dBc/Hz, making it ideal for use in applications that require high-quality and low-jitter clock signals.

In summary, the CVCO55BE-2100-2200 is a powerful and reliable voltage-controlled oscillator (VCO) designed for use in a wide range of applications from communications systems to frequency filters and modulators. The device utilizes PWM technology to precisely control its frequency, as well as a tracking feature which enables the device to “lock” onto a desired output frequency and maintain it over a wide temperature range. The device is also suited for applications that require low-jitter clock signals, and features an extremely low RMS phase noise of -94 dBc/Hz.
