ASM3P2274A

Low Power 4X Multiplier EMI Reduction IC

Features

The ASM3P2274A uses the most efficient and optimized

modulation profile approved by the FCC and is

implemented by using a proprietary all digital method.

Generates a 4X EMI optimized clock signal at the

output.

Integrated loop filter components.

Operates with a 3.3 / 2.5V Supply.

Low power CMOS design.

Input frequency range: 12MHz to 30MHz for 2.5V.

: 12MHz to 30MHz for 3.3V.

Frequency deviation: -1.5% (Typ) @66MHz Output

Frequency.

Available in 6-pin TSOT-23 Package.

The ASM3P2274A 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’.

Product Description

Applications

The ASM3P2274 is

a versatile Spread Spectrum

The ASM3P2274A is targeted towards all portable

devices with very low power requirements like MP3

players,MFP, LCD Panel Module and digital still cameras.

Frequency Modulator designed specifically for a wide

range of clock frequencies. It provides a 4x Spread

Spectrum Modulated output from an input clock source.

The ASM3P2274A reduces electromagnetic interference

(EMI) at the clock source, allowing system wide reduction

of EMI of all clock dependent signals. The ASM3P2274A

allows significant system cost savings by reducing the

number of circuit board layers ferrite beads, shielding

that are traditionally required to pass EMI regulations.
