ASM3P2853A  
Peak EMI Reducing Solution  
Features  
Generates an EMI optimized clock signal at output.  
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 by increasing a  
signal’s bandwidth is called spread spectrum clock  
generation.  
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.
