Working Principles

The AD9854ASVZ utilizes a DDS (Direct Digital Synthesis) technique to generate signals. It consists of a phase accumulator, a sine lookup table, and a digital-to-analog converter (DAC). The phase accumulator generates a digital phase value, which is used to index the sine lookup table. The values retrieved from the lookup table are then converted to analog signals by the DAC, resulting in the desired output frequency.
