onsemi ASM3P2274A
The ASM3P2274A reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of all clock dependent signals. The ASM3P2274A 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 ASM3P2274A uses the most efficient and optimized modulation profile approved by the FCC and is implemented by using a proprietary all digital method.| Part No. | ASM3P2274A |

DESCRIPTION
The ASM3P2274 is a versatile Spread Spectrum Frequency Modulator designed specifically for a wide range of clock frequencies. It provides a 4x Spread Spectrum Modulated output from an input clock source. The ASM3P2274A 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 t
