DESCRIPTION
Output waveforms can be phase or frequency modulated. Digital output frequencies are restricted to the Nyquist limit. The user selects the numeric format. A valid transformed result is seen at the output after 22 clock cycles and will continue upon every clock cycle thereafter. 15-bit amplitude and 32-bit phase data are input into the L2340 to produce an output of 16-bit rectangular data. The user may select the data format to either 16-bit offset binary or 15-bit unsigned magnitude format. High accuracy phase increment values with minimal accumulation error is accomplished by use of a 32-bit phase accumulator. The phase accumulator structure supports frequency or phase modulation and is selected by ENP1-0 and accumulator controls FM and PM. FEATURES
