P2781/82/84 General Purpose EMI Reduction IC Features • Provides up to 15dB of EMI suppression • FCC approved method of EMI attenuation • Generates a 1X, 2X, and 4X low EMI spread spectrum clock of the input frequency • Input frequency range from 3 to 78MHz • External loop filter for spread % adjustment • Spreading ranges from ±0.
25% to ±5.
0% • Ultra low cycle-to-cycle jitter • Zero-cycle slip • 3.
3V operating voltage range • Ultra-low power CMOS design • P278xA is available in an 8 pin SOIC Package source, which provides system wide reduction of EMI of all clock dependent signals.
The P278xA allows significant system cost savings by reducing the number of circuit board layers and shielding ...
