NB2879A  
Low Power, Reduced EMI  
Clock Synthesizer  
The NB2879A is a versatile spread spectrum frequency modulator  
designed specifically for a wide range of clock frequencies. The  
NB2879A reduces ElectroMagnetic Interference (EMI) at the clock  
source, allowing system wide reduction of EMI of all clock dependent  
signals. The NB2879A allows significant system cost savings by  
reducing the number of circuit board layers, ferrite beads and  
shielding that are traditionally required to pass EMI regulations.  
The NB2879A uses the most efficient and optimized modulation  
profile approved by the FCC and is implemented by using a  
proprietary all digital method.  
The NB2879A modulates the output of a single PLL in order to  
“spread” the bandwidth of a synthesized clock, and more importantly,  
decreases the peak amplitudes of its harmonics. This results in  
significantly lower system EMI compared to the typical narrow band  
signal produced by oscillators and most frequency generators.  
Lowering EMI by increasing a signal’s bandwidth is called ‘spread  
spectrum clock generation’.
