The DDS chip produces standard sine and triangle waveforms n Short circuit protection for resistive and with high frequency resolution and at a low cost. The true point-by-point AWG implementation (Fig 2) capacitive loads on outputs and overvoltage offers improved signal integrity for arbitrary waveforms by producing significantly less jitter and distortion protection on inputs compared to a DDS-based architecture. Custom arbitrary waveform generation is implemented with a variable clock signal to reproduce each point stored in memory without skipping or repeating data points, a problem typically found in DDS based designs with fixed reference clocks.
