ASM3P2853A Peak EMI Reducing Solution Features • Generates an EMI optimized clock signal at output. • Input frequency: 25MHz. • Frequency outputs: o USB Clock (48MHz unmodulated) o 50MHz (modulated), ±1% centre spread • Modulation rate: 39KHz. • Spread Spectrum ON/OFF control • Supply voltage range 2.5V ± 5%. • Available in 8-Pin SOIC package. Product Description The ASM3P2853A is a versatile spread spectrum frequency modulator. The ASM3P2853A reduces electromagnetic interference (EMI) at the clock source. The ASM3P2853A allows significant system cost savings by reducing the number of circuit board layers and shielding that are required to pass EMI regulations. The ASM3P2853A modulates the output of PLL in order to spread the bandwidth of a synthesized clock, thereby decreasing 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 clock generators. Lowering EMI b.
