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
HSP45116 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.
