Numerically Controlled

Oscillator/Modulator

Features

• This Circuit is Processed in Accordance to MIL-STD-883

and is Fully Conformant Under the Provisions of

Paragraph 1.2.1.

The Intersil HSP45116/883 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 HSP45116/883 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.

• NCO and CMAC on One Chip

• 15MHz and 25.6MHz Versions

• 32-Bit Frequency Control

• 16-Bit Phase Modulation

• 16-Bit CMAC

• 0.006Hz Tuning Resolution at 25.6MHz

• 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 0.006Hz at 25.6MHz. 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

The output vector from the Sine/Cosine Section is one of the

inputs to the Complex Multiplier/Accumulator. The CMAC mul-

tiplies 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.

• Phase Shifter

• Polar to Cartesian Conversions

PACKAGE

A quadrature down converter can be implemented by

loading a center frequency into the Phase/Frequency

Control Section. The signal to be downconverted 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.
