ASM3P2579A  
Low Power Peak EMI Reducing Solution  
Features  
The ASM3P2579A uses the most efficient and optimized  
modulation profile approved by the FCC and is  
implemented by using a proprietary all digital method.  
•
Generates an EMI optimized clock signal at the  
output.  
•
•
•
•
•
Integrated loop filter components.  
Operates with a 3.3 / 2.5V Supply.  
Operating current less than 4mA.  
Low power CMOS design.  
Input frequency range: 12MHz to 30MHz for 2.5V  
: 12MHz to 30MHz for 3.3V  
Generates a 1X low EMI spread spectrum clock of  
the input frequency.  
Spread Spectrum Enable Control.  
Frequency deviation: ±1% @ 24MHz  
Available in 6 pin TSOT-23, 8 pin SOIC and 8 pin  
TSSOP Packages.  
The ASM3P2579A 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’.  
•
•
•
•
Applications  
The ASM3P2579A is targeted towards all portable  
devices with very low power requirements like MP3  
players and digital still cameras.  
Product Description  
The ASM3P2579A is  
a versatile spread spectrum  
Key Specifications  
frequency modulator designed specifically for a wide  
range of clock frequencies. The ASM3P2579A reduces  
electromagnetic interference (EMI) at the clock source,  
allowing system wide reduction of EMI of all clock  
dependent signals. The ASM3P2579A allows significant  
system cost savings by reducing the number of circuit  
board layers ferrite beads, shielding that are traditionally  
required to pass EMI regulations.
