The PDSP16350 provides an integrated solution to the
need for very accurate, digitised, sine and cosine waveforms.
Both these waveforms are produced simultaneously, with 16
bit amplitude accuracy, and are synthesised using a 34 bit
phase accumulator. The more significant bits of this provide
16 bits of phase accuracy for the sine and cosine look up
tables.
With a 20 MHz system clock, waveforms up to 10 MHz can
be produced, with 0.001 Hz resolution. If frequency modula-
tion is required with no discontinuities, the phase increment
value can be changed linearly on every clock cycle. Alterna-
tively absolute phase jumps can be made to any phase value.
The provision of two output multipliers allows the sine and
cosine waveforms to be amplitude modulated with a 16 bit
value present on the input port. This option can also be used
to generate the in-phase and quadrature components from an
incoming signal. This I/Q split function is required by systems
which employ complex signal processing.
