November 2006 rev 0.2 Low Frequency EMI Reduction IC Features FCC approved method of EMI attenuation Provides up to 20dB of EMI suppression Generates a low EMI spread spectrum clock of the input frequency Optimized for 10MHz to 35MHz input frequency range Internal loop filter minimizes external components and board space 4 selectable spread ranges SSON control pin for spread spectrum enable and disable options Low Cycle-to-cycle jitter Wide operating range (3V to 5V) 16mA output drives TTL or CMOS compatible outputs Low power CMOS design Available in 8 pin SOIC and TSSOP Packages P2010A electromagnetic interference (EMI) at the clock source which provides system wide reduction of EMI of all clock dependent signals. The P2010A allows significant system cost savings by reducing the number of circuit board layers and shielding that are traditionally required to pass EMI regulations. The P2010A uses the most efficient and optimized modulation profile approved by the FCC and is implemented in a proprietary all-digital method. The P2010A 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”. Product Description The P2010A ……
