NB2869A
Low Power, Reduced EMI
Clock Synthesizer
The NB2869A is a versatile spread spectrum frequency modulator
designed specifically for a wide range of clock frequencies. The
NB2869A reduces ElectroMagnetic Interference (EMI) at the clock
source, allowing system wide reduction of EMI of all clock dependent
signals. The NB2869A 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 NB2869A uses the most efficient and optimized modulation
profile approved by the FCC and is implemented by using a
proprietary all digital method.
The NB2869A 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’.
The NB2869A is targeted towards all portable devices with very
low power requirements like MP3 players and digital still cameras.
