Description

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).

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-pin plastic pin grid array package (PPGA), 120-pin ceramic pin grid array package (CPGA), 120-pin MQFP to PPGA (MPGA) package, and 120-pin metric quad flatpack package (MQFP)

Applications

• Scan conversion (phased array to raster)

• Vector magnitude estimation

• Range and bearing derivation

• Spectral analysis

• Digital waveform synthesis, including quadrature functions

• Digital modulation and demodulation
