The ASM3P2853A is a versatile spread spectrum frequency modulator. Santa Clara CA Tel: 408-855-4900 Fax: 408-855-

Generates an EMI optimized clock signal at output. Input frequency: 25 MHz. Frequency outputs: o o USB Clock (48 MHz unmodulated) 50 MHz (modulated), ±1% centre spread 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 mos.
