6 ASM3P2969A Low Power Peak EMI Reducing Solution Features Generates an EMI optimized clock signal at the output.
Integrated loop filter components.
Operates with a 3.
3V / 2.
5V supply.
Operating current less than 4mA.
Low power CMOS design.
Input frequency range: 6MHz to 12MHz for 2.
5V : 6MHz to 13MHz for 3.
3V Generates a 1X low EMI spread spectrum clock of the input frequency.
Frequency deviation: ±1% @ 10MHz Available in 6 pin TSOT-23, 8 pin SOIC and 8 pin TSSOP Packages.
The ASM3P2969A uses the most efficient and optimized modulation profile approved by the FCC and is implemented by using a proprietary all digital method.
The ASM3P2969A 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 fre...
