L2330  
Coordinate Transformer  
DEVICES INCORPORATED  
FEATURES  
DESCRIPTION  
The L2330 is a coordinate transformer seen at the output after 22 clock cycles  
Rectangular-to-PolarorPolar-to-  
Rectangular at 50 MHz  
that converts bidirectionally between  
Rectangular and Polar coordinates.  
and will continue upon every clock  
cycle thereafter.  
PerformsDirectDigitalSynthesis  
(DDS) functions along with PM and  
FM Modulation  
When in Rectangular-to-Polar mode,  
When in Rectangular-to-Polar mode,  
the L2330 is able to retrieve phase and the user inputs a 16-bit Rectangular  
magnitude information or backward coordinate and the output generates a  
map from a rectangular raster display 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 2π so it may be  
regarded as either unsigned or two’s  
complement format.  
When in Polar-to-Rectangular mode,  
the L2330 is able to execute direct  
digital waveform synthesis and  
modulation. Real-time image-space  
conversions are achieved from radi-  
ally-generated images, such as RADAR,  
SONAR, and ultrasound to raster  
display formats.  
When in Polar-to-Rectangular mode,  
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 complement  
or sign-and-magnitude Cartesian data  
format.  
Functional Description  
The L2330 converts bidirectionally  
between Rectangular (Cartesian) and  
Polar (Phase and Magnitude) coordi-  
nates. The user selects the numeric  
format. A valid transformed result is
