Voltage controlled oscillators, or VCOs, are electronic circuits which, as the name suggests, use voltage as a means of controlling the frequency and/or phase of an oscillation. The CVCO55BE-1785-1900 is one such type of VCO, developed, manufactured and distributed by Catalyst Semiconductor, a Silicon Valley-based firm.
Application Field
This type of VCO is a low-frequency oscillator designed for use in such applications as wireless infrastructures, 3G/4G cellular phone systems and Ethernet networks. It features a low power consumption, a wide frequency range and a small package size. It can also be used for low-power clock applications, such as clocks in computers, digital watches and other time-keeping devices. In addition, its low frequency range allows it to be used in systems aside from a clock, such as an FM stereo modulator.Working Principle
The working principle of the CVCO55BE-1785-1900 involves the use of a voltage-to-frequency (V/F) converter, which converts an input voltage into a varying output frequency. The VCO has an adjustable bias current, meaning the frequency can be changed by adjusting the applied bias current. This adjusts the relationship between the input voltage and the output frequency. The output frequency of the VCO is thus determined by the input voltage, and this can be in turn controlled by an external source, such as a digital-to-analog converter.Conclusion
The CVCO55BE-1785-1900 is a low-frequency voltage-controlled oscillator designed for use in various applications such as wireless infrastructures and Ethernet networks. Its small package size and low power consumption make it suitable for a wide range of applications. It works by using a voltage-to-frequency converter which converts an input voltage into a varying output frequency and an adjustable bias current, which adjusts the relationship between the input voltage and the output frequency.The specific data is subject to PDF, and the above content is for reference
