ASM3P2598A

Low Power Peak EMI Reducing Solution

Features

The ASM3P2598A uses the most efficient and optimized

modulation profile approved by the FCC and is

implemented by using a proprietary all digital method.

•

Generates a 1X low EMI optimized clock signal at the

output.

•

Integrated loop filter components.

Operates with a 3.3 / 2.5V Supply.

Operating current less than 5mA.

Low power CMOS design.

Input frequency range

60MHz to 120MHz for 2.5V

60MHz to 120MHz for 3.3V

Frequency deviation: ±1.5(Typ) @85MHz Output

frequency.

The ASM3P2598A 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’.

•

Available in 6-pin TSOT-23 Package.

Applications

Product Description

The ASM3P2598A is targeted towards all portable

devices with very low power requirements like MP3

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

The ASM3P2598A is

a versatile spread spectrum

frequency modulator designed specifically for a wide

range of clock frequencies. The ASM3P2598A reduces

electromagnetic interference (EMI) at the clock source,

allowing system wide reduction of EMI of all clock

dependent signals. The ASM3P2598A allows significant

system cost savings by reducing the number of circuit

board layers ferrite beads, shielding that are traditionally

required to pass EMI regulations.
