ASM3P2969A

Low Power Peak EMI

Reducing Solution

Description

The ASM3P2969A is a versatile spread spectrum frequency

modulator designed specifically for a wide range of clock frequencies.

The ASM3P2969A reduces electromagnetic interference (EMI) at the

clock source, allowing system wide reduction of EMI of all clock

dependent signals. The ASM3P2969A allows significant system cost

savings by reducing the number of circuit board layers, ferrite beads

and shielding that are traditionally required to pass EMI regulations.

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 frequency generators.

Lowering EMI by increasing a signal’s bandwidth is called ‘spread

spectrum clock generation.’
