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
