HSP45116 Data Sheet May 1999 File Number 2485.7 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 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.
