The working principle of this oscillator is based on the use of Saw resonators. These are made up of a complex substrate material such as lithium niobate or aluminum nitride. These substrates are subjected to an electrical field which vibrates the material at an extremely high frequency. This vibration generates a low-noise, periodic waveform that is then passed through a filter, which removes unwanted signals and shapes the waveform into the desired frequency. The filtered signal is then amplified and converted into an analog signal for the external system.

The AX7DCF4-312.5000C oscillator offers a great deal of versatility and can be used in a wide variety of applications. It offers low phase noise performance and has digitally controllable output and phases, making it suitable for applications requiring precise adjustment of parameters. Furthermore, its operation is based on Saw resonator technology, which has been proven to be reliable and stable.
