资 源 简 介

The Intersil HSP45116 combines a high performancequadrature Numerically Controlled Oscillator (NCO) and ahigh speed 16-bit Complex MulTIplier/Accumulator (CMAC)on a single IC. This combinaTIon of funcTIons allows acomplex vector to be mulTIplied by the internally generated(cos, sin) vector for quadrature modulation anddemodulation. As shown in the Block Diagram, theHSP45116 is divided into three main sections. ThePhase/Frequency Control Section (PFCS) and theSine/Cosine Section together form a complex NCO. TheCMAC multiplies the output of the Sine/ Cosine Section withan external complex vector.
