NB2779A

Low Power, Reduced EMI

Clock Synthesizer

The NB2779A is a versatile spread spectrum frequency modulator

designed specifically for a wide range of clock frequencies. The

NB2779A reduces ElectroMagnetic Interference (EMI) at the clock

source, allowing system wide reduction of EMI of all clock dependent

signals. The NB2779A 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 NB2779A uses the most efficient and optimized modulation

profile approved by the FCC and is implemented by using a

proprietary all digital method.

The NB2779A 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’.
