TMC2330A - Fairchild Semiconductor

TMC2330A Coordinate Transformer 16 x 16 Bit/ 40 MOPS

The TMC2330A 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 TMC2330A can extract phase and magnitude information or backward “map” from a rectangular raster display to a radial (e.g., range-and-azim.

Features

• Rectangular-to-Polar or Polar-to-Rectangular conversion at guaranteed 40 MOPS pipelined throughput rate
• Polar data: 16-bit magnitude, 32-bit input/16-bit output phase
• 16-bit user selectable two’s complement or sign-andmagnitude rectangular data formats
• Input register clock enables and asynchronous output enables simplify interfacing
• User-configurable phase accumulator for waveform synthesis and amplitude, frequency, or phase modulation
• Magnitude output data overflow flag (in Polar-toRectangular mode)
• Low power consumption CMOS process
• Single +5V power supply
• Available in a 120-p.
