16-Bit Numerically Controlled Oscillator
The Intersil HSP45106/883 is a high performance 16-bit
quadrature Numerically Controlled Oscillator (NCO16). The
NCO16 simplifies applications requiring frequency and
phase agility such as frequency-hopped modems, PSK
modems, spread spectrum communications, and precision
signal generators. As shown in the Block Diagram, the
HSP45106/883 is divided into a Phase/Frequency Control
Section (PFCS) and a Sine/Cosine Section.
The inputs to the Phase/Frequency Control Section consist
of a microprocessor interface and individual control lines.
The frequency resolution is 32 bits, which provides for
resolution of better than 0.006Hz at 25.6MHz. User
programmable center frequency and offset frequency
registers give the user the capability to perform phase
coherent switching between two sinusoids of different
frequencies. Further, a programmable phase control register
allows for phase control of better than 0.006o. In applications
requiring up to 8 level PSK, three discrete inputs are
provided to simplify implementation.
The output of the PFCS is a 32-bit phase argument which is
input to the Sine/Cosine Section for conversion into
sinusoidal amplitude. The outputs of the Sine/Cosine
Section are two 16-bit quadrature signals. The spurious free
dynamic range of this complex vector is greater than 90dBc.
For added flexibility when using the NCO16 in conjunction
with DAC’s, a choice of either parallel of serial outputs with
either two’s complement or offset binary encoding is
provided. In addition, a synchronization signal is available
which signals serial word boundaries.
