Working Principles

The AD9852ASTZ utilizes direct digital synthesis (DDS) technique to generate precise and stable waveforms. It consists of a phase accumulator, a digital-to-analog converter (DAC), and a reconstruction filter. The phase accumulator generates a digital representation of the desired waveform's phase, which is then converted into an analog signal by the DAC. The reconstructed analog signal is filtered to remove any unwanted harmonics or noise, resulting in a clean output waveform.
