Overview

L2330 DEVICES INCORPORATED Coordinate Transformer L2330 DEVICES INCORPORATED Coordinate Transformer DESCRIPTION The L2330 is a coordinate transformer that converts bidirectionally between Rectangular and Polar coordinates.
When in Rectangular-to-Polar mode, the L2330 is able to retrieve phase and magnitude information or backward map from a rectangular raster display to a radial data set.
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 radially-generated images, such as RADAR, SONAR, and ultrasound to raster display formats.
Functional Description The L2330 converts bidirectionally between Rectangular (Cartesian) and Polar (Phase and Magnitude) 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.
When in Rectangular-to-Polar mode, 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-andmagnitude 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 user inputs 16-bit Polar Magnitude and 32-bit Phase data and the output generates a 16-bit Rectangular coordinate.
The use may select the data format to be either two’s complement or sign-and-magnitude Cartesian data format.
