Oscillators

CWX825-29.4912M is a series of voltage-controlled crystal oscillators (VCXOs) that use a high-stability (Relatively Low Aging Rate) crystal and high-performance capacitors to oscillate accurately and stably over a wide frequency range. The CWX825-29.4912M is often used in frequency synthesis systems, digital telecommunication systems, Wi-Fi networks, broadcast television systems, wireless base stations, cellular base stations, and commercial electronics.

Application field

The CWX825-29.4912M is mainly used in frequency synthesis systems to provide signals in the range of a few hundred hertz to around 40 megahertz, which are needed for many microwave communication applications. It can also be used to control the output frequency of a radio transmitter, providing a frequency-synthesized signal to the receiver. In addition, it can be used for digital telecommunication systems, Wi-Fi networks, broadcast television systems, wireless base stations, cellular base stations, and commercial electronics. Moreover, this series of VCXOs has low phase noise, which is necessary for signal transmission.

Working principle

The CWX825-29.4912M is based on a differential oscillator circuit, which is made by combining two oscillators, one oscillator is the reference oscillator, and the other oscillator is the control oscillator. The reference oscillator produces a stable frequency signal. The control oscillator is made to oscillate at the same frequency as the reference oscillator, but with slightly different phase. By changing the phase of the control oscillator, the frequency of the signal can be adjusted. The output of the signal is then derived from the phase difference between the two oscillators. The frequency of the signal can be controlled up or down with the voltage. With the high-frequency range and high-stability, the CWX825-29.4912M can be used for multiple applications and is widely used in many electronic systems.
