NB2669A
Low Power, Reduced EMI
Clock Synthesizer
designed specifically for a wide range of clock frequencies. The
NB2669A reduces ElectroMagnetic Interference (EMI) at the clock
source, allowing system wide reduction of EMI of all clock dependent
signals. The NB2669A 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.
profile approved by the FCC and is implemented by using a
proprietary all digital method.
“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’.
