简  介:April 2008 rev 1.6 Low Power EMI Reduction IC Features FCC approved method of EMI attenuation Provides up to 15dB EMI reduction Generates a 1x, 2x and 4x low EMI spread spectrum clock of the input frequency 1x: ASM3P2811A/B 2x: ASM3P2812A/B 4x: ASM3P2814A/B Optimized for input frequency range from 10MHz to 40 MHz Internal loop filter minimizes external components and board space Selectable spread options: Down Spread and Center Spread 8 frequency deviation selections: ±0.625% to -3.5% Low inherent Cycle-to-Cycle Jitter 3.3V Operating Voltage CMOS/TTL compatible inputs and outputs. Pin-out compatible with Cypress CY25811, CY25812 and CY25814 Commercial and Industrial temperature range Available in 8-pin SOIC and TSSOP Packages ASM3P2811A/B ASM3P2812A/B ASM3P2814A/B and Center Spread, and percentage deviation range from ±0.625% to -3.5%. The ASM3P28XX reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals. The ASM3P28XX allows significant system cost savings by reducing the number of circuit board layers, ferrite beads, shielding, and other passive components that are traditionally required to pass EMI regulations. The ASM3P28XX 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 nar……
