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.  
o
Applications  
• Direct Digital Synthesis  
• Modulation  
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.  
• PSK Communications  
• Related Products  
- HI5731 12-Bit, 100MHz D/A Converter  
The NCO12 has applications as a Direct Digital Synthesizer  
and modulator in low cost digital radios, satellite terminals,  
and function generators.
