12-Bit Numerically Controlled Oscillator

Features

The Intersil HSP45102 is Numerically Controlled Oscillator

(NCO12) with 32-bit frequency resolution and 12-bit output.

With over 69dB of spurious free dynamic range and worst

case frequency resolution of 0.009Hz, the NCO12 provides

significant accuracy for frequency synthesis solutions at a

competitive price.

• 33MHz, 40MHz Versions

• 32-Bit Frequency Control

• BFSK, QPSK Modulation

• Serial Frequency Load

• 12-Bit Sine Output

The frequency to be generated is selected from two frequency

control words. A single control pin selects which word is used

to determine the output frequency. Switching from one

frequency to another occurs in one clock cycle, with a 6 clock

pipeline delay from the time that the new control word is

loaded until t3-he new frequency appears on the output.

• Offset Binary Output Format

• 0.009Hz Tuning Resolution at 40MHz

• Spurious Frequency Components <-69dBc

• Fully Static CMOS

• Low Cost

Two pins, P0-1, are provided for phase modulation. They are

encoded and added to the top two bits of the phase

accumulator to offset the phase in 90° increments.

• Pb-Free Plus Anneal Available (RoHS Compliant)

Applications

The 13-bit output of the Phase Offset Adder is mapped to

the sine wave amplitude via the Sine ROM. The output data

format is offset binary to simplify interfacing to D/A

converters. Spurious frequency components in the output

sinusoid are less than -69dBc.

• Direct Digital Synthesis

• Modulation

• PSK Communications

The NCO12 has applications as a Direct Digital Synthesizer

and modulator in low cost digital radios, satellite terminals,

and function generators.
