TMC2330AH5C

The TMC2330AH5C VLSI circuit converts bidirectionally between Cartesian (real and imaginary) and Polar (magnitude and phase) coordinates at up to 40 MOPS (Million Operations Per Second).

In its Rectangular-to-Polar mode, the TMC2330AH5C can extract phase and magnitude information or backward "map" from a rectangular raster display to a radial (e.g., range-and-azimuth) data set.
The Polar-to-Rectangular mode executes direct digital waveform synthesis and modulation. The TMC2330A greatly simplifies real-time image-space conversion between the radially-generated image scan data found in radar, sonar, and medical imaging systems, and raster display formats.
All input and output data ports are registered, and a new transformed data word pair is available at the output every clock cycle. The user-configurable phase accumulator structure, input clock enables, and asynchronous three-state output bus enables simplify interfacing. All signals are TTL compatible.
Fabricated in a submicron CMOS process, the TMC2330AH5C operates at up to the 40 MHz maximum clock rate over the full commercial (0 to 70°C) temperature and supply voltage ranges, and is available in 120-pin plastic pin grid array, 120-pin ceramic pin grid array, 120-pin metric quad flatpack to PPGA package, and 120-pin metric quad flatpack packages.
