Working Principle

The DSC1001CI2-010.4857T oscillator features a phase-locked loop (PLL) frequency synthesizer with a variable oscillator core. The oscillator core is digitally controlled via an on-board microcontroller, which can be programmed to achieve a wide range of frequencies and accuracies. The variable oscillator core is connected to an op-amp feedback circuit, which produces an analog output signal modulated by the PLL.The digital control system allows for precise adjustment and frequency locking of the final output signal. The oscillator is programmed to achieve a high level of phase noise performance, and can generate frequencies up to 200 MHz with an accuracy of less than 0.1 Hz. The device is also temperature compensated and rated for operation over a wide range of temperatures.
