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
