FN2485.7
Numerically Controlled
Oscillator/Modulator
The Intersil HSP45116 combines a high performance
quadrature Numerically Controlled Oscillator (NCO) and a
high speed 16-bit Complex Multiplier/Accumulator (CMAC)
on a single IC. This combination of functions allows a
complex vector to be multiplied by the internally generated
(cos, sin) vector for quadrature modulation and
demodulation. As shown in the Block Diagram, the
www.DataSheHeSt4PU4.c5o1m16 is divided into three main sections. The
Phase/Frequency Control Section (PFCS) and the
Sine/Cosine Section together form a complex NCO. The
CMAC multiplies the output of the Sine/ Cosine Section with
an external complex vector.
The inputs to the Phase/Frequency Control Section consist
of a microprocessor interface and individual control lines.
The phase resolution of the PFCS is 32 bits, which results in
frequency resolution better than 0.008Hz at 33MHz. The
output of the PFCS is the argument of the sine and cosine.
The spurious free dynamic range of the complex sinusoid is
greater than 90dBc.
The output vector from the Sine/Cosine Section is one of the
inputs to the Complex Multiplier/Accumulator. The CMAC
multiplies this (cos, sin) vector by an external complex vector
and can accumulate the result. The resulting complex vectors
are available through two 20-bit output ports which maintain
the 90dB spectral purity. This result can be accumulated
internally to implement an accumulate and dump filter.
A quadrature down converter can be implemented by
loading a center frequency into the Phase/Frequency
Control Section. The signal to be down converted is the
Vector Input of the CMAC, which multiplies the data by the
rotating vector from the Sine/Cosine Section. The resulting
complex output is the down converted signal.
