HSP45116

Data Sheet

J uly 2004

FN2485.8

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.

Numerically Controlled

Os cillator/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.

Features

• NCO and CMAC on One Chip

• 15MHz, 25.6MHz, 33MHz Versions

• 32-Bit Frequency Control

• 16-Bit Phase Modulation

• 16-Bit CMAC

• 0.008Hz Tuning Resolution at 33MHz

• Spurious Frequency Components < -90dBc

• Fully Static CMOS

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.

Applications

• Frequency Synthesis

• Modulation - AM, FM, PSK, FSK, QAM

• Demodulation, PLL

• Phase Shifter

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.

• Polar to Cartesian Conversions
