Low Power EMI Reduction IC  
Features  
and Center Spread, and percentage deviation range from  
±0.625% to -3.5%.  
FCC approved method of EMI attenuation  
Provides up to 15dB EMI reduction  
Generates a 1x, 2x and 4x low EMI spread  
spectrum clock of the input frequency  
1x: ASM3P2811A/B  
The ASM3P28XX reduces electromagnetic interference  
(EMI) at the clock source, allowing system wide reduction  
of EMI of down stream clock and data dependent  
signals. The ASM3P28XX allows significant system cost  
savings by reducing the number of circuit board layers,  
ferrite beads, shielding, and other passive components  
that are traditionally required to pass EMI regulations.  
2x: ASM3P2812A/B  
4x: ASM3P2814A/B  
Optimized for input frequency range from  
10MHz to 40 MHz  
Internal loop filter minimizes external  
components and board space  
Selectable spread options:  
The ASM3P28XX 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 to the typical narrow band signal produced  
by oscillators and most frequency generators. Lowering  
EMI by increasing a signal’s bandwidth is called ‘spread  
spectrum clock generation’.  
Down Spread and Center Spread  
8 frequency deviation selections:  
±0.625% to -3.5%  
Low inherent Cycle-to-Cycle Jitter  
3.3V Operating Voltage  
CMOS/TTL compatible inputs and outputs.  
Pin-out compatible with Cypress CY25811,  
CY25812 and CY25814  
The ASM3P28XX uses the most efficient and optimized  
modulation profile approved by the FCC and is  
implemented in a proprietary all-digital method.  
Commercial and Industrial temperature range  
Available in 8-pin SOIC and TSSOP Packages  
Applications  
Product Description  
The ASM3P28XX is targeted towards EMI management  
for memory and LVDS interfaces in mobile graphic  
chipsets and high-speed digital applications such as PC  
peripheral devices, consumer electronics, and embedded  
controller systems.  
The ASM3P28XX devices are versatile spread spectrum  
frequency modulators designed specifically for a wide  
range of input clock frequencies from 10MHz to 40MHz.  
Refer Input / Output Frequency Range Selection Table.  
The ASM3P28XX can generate an EMI reduced clock  
from crystal, ceramic resonator, or system clock. The  
ASM3P28XX-A and the ASM3P28XX-B offer various  
combinations of spread options and percentage  
deviations. Refer Frequency Deviation and Spread  
Selection Table. These combinations include Down
