Functional Description
The TMC2330A converts between Rectangular (Cartesian)
and Polar (Phase and Magnitude) coordinate data word pairs.
The user selects the numeric format and transformation to be
performed (Rectangular-To-Polar or Polar-To-Rectangular),
and the operation is performed on the data presented to the
inputs on the next clock. The transformed result is then
available at the outputs 22 clock cycles later, with new out-
put data available every 20ns with a 40 MHz clock. All input
and output data ports are registered, with input clock enables
and asynchronous high-impedance output enables to sim-
plify connections to system buses.
When executing a Rectangular-To-Polar conversion, the input
ports accept 16-bit Rectangular coordinate words, and the out-
put ports generate 16-bit magnitude and 16-bit phase data. The
user selects either two’s complement or sign-and-magnitude
Cartesian data format. Polar magnitude data are always in
magnitude format only. Since the phase angle word is modulo
2π, it may be regarded as either unsigned or two’s complement
format (Tables 1 and 2).
In Polar-To-Rectangular mode, the input ports accept 16-bit
Polar magnitude and 32-bit phase data, and the output ports
produce 16-bit Rectangular data words. Again, the user
selects between two’s complement or sign-and-magnitude
Cartesian data format.
