The L2340 automatically generates quadrature matched pairs of 16-bit sine and cosine waves in DAC- compatible 16-bit offset binary format with15-bit amplitude and 32-bit phase inputs. Output waveforms can be phase or frequency modulated. Digital output frequencies are restricted to the Nyquist limit. Functional Description The L2340 converts Polar (Phase and Magnitude) data into Rectangular (Cartesian) coordinates. 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 accom- plished by use of a 32-bit phase accumulator. The phase accumulator structure supports frequency or phase modula- tion and is selected by ENP1-0 and accumulator controls FM and PM.
