L2330

The L2330 converts bidirectionally between Rectangular (Cartesian) and Polar (Phase and Magnitude) coordi- nates.  The user selects the numeric format.  A valid transformed result isseen at the output after 22 clock cycles and will continue upon every clock cycle thereafter.

When in Rectangular-to-Polar mode L2330, the user inputs a 16-bit Rectangular coordinate and the output generates a Polar transformation with 16-bit magnitude and 16-bit phase.  The user may select the data format to be either two!s complement or sign-and magnitude Cartesian data format. Polar Magnitude data is always in magnitude format only.  Polar Phase Angle data is modulo 2? so it may be regarded as either unsigned or two! complement format.

When in Polar-to-Rectangular mode L2330, the user inputs 16-bit Polar Magnitude  and 32-bit Phase data and the output generates a 16-bit Rectangular coordi- nate.  The use may select the data format to be either two!s complemen or sign-and-magnitude Cartesian data format.
