TMC2330A

Coordinate Transformer

16 x 16 Bit, 40 MOPS

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-and-

magnitude 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-to-

Rectangular 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)

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).

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-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 trans-

formed 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 TMC2330A

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.
