ASM3P2531A  
Low Frequency EMI Reduction  
Features  
dependent signals. It allows significant system cost  
savings by reducing the number of circuit board layers  
and shielding traditionally required to pass EMI  
regulations.  
FCC approved method of EMI attenuation.  
Generates a low EMI spread spectrum of the  
input clock frequency.  
Optimized for input frequency range between  
27MHz – 55MHz.  
Internal loop filter minimizes external  
components and board space.  
The ASM3P2531A modulates the output of a single PLL  
in order to spread the bandwidth of a synthesized clock,  
thereby decreasing the peak amplitudes of its harmonics.  
This result 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.  
Frequency Deviation: ±1.7%.  
Low inherent Cycle-to-cycle jitter.  
3.3 V ± 0.3V Operating Voltage.  
Ultra low power CMOS design:3.0 mA @ 3.3 V.  
Supports notebook VGA and other LCD timing  
controller applications.  
The ASM3P2531A uses the most efficient and optimized  
modulation profile approved by the FCC and is  
implemented by using a proprietary all-digital method.  
Available in 8-pin SOIC and TSSOP Packages.  
Product Description  
Applications  
The ASM3P2531A is  
a versatile spread spectrum  
frequency modulator designed specifically for a wide  
range of clock frequencies. It reduces electromagnetic  
interference (EMI) at the clock source allowing system-  
wide reduction of EMI of downstream clock and data  
The ASM3P2531A is targeted toward the notebook VGA  
chip and other displays using an LVDS interface, PC  
peripheral devices, and embedded systems.
