Low Power EMI Reduction IC

Features

and Center Spread, and percentage deviation range from

±0.625% to -3.5%.

•

FCC approved method of EMI attenuation

Provides up to 15dB EMI reduction

Generates a 1x, 2x and 4x low EMI spread

spectrum clock of the input frequency

• 1x: ASM3P2811A/B

The ASM3P28XX reduces electromagnetic interference

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

of EMI of down stream clock and data dependent

signals. The ASM3P28XX allows significant system cost

savings by reducing the number of circuit board layers,

ferrite beads, shielding, and other passive components

that are traditionally required to pass EMI regulations.

• 2x: ASM3P2812A/B

• 4x: ASM3P2814A/B

•

Optimized for input frequency range from

10MHz to 40 MHz

Internal loop filter minimizes external

components and board space

Selectable spread options:

The ASM3P28XX 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’.

• Down Spread and Center Spread

8 frequency deviation selections:

• ±0.625% to -3.5%

•

Low inherent Cycle-to-Cycle Jitter

3.3V Operating Voltage

CMOS/TTL compatible inputs and outputs.

Pin-out compatible with Cypress CY25811,

CY25812 and CY25814

The ASM3P28XX uses the most efficient and optimized

modulation profile approved by the FCC and is

implemented in a proprietary all-digital method.

•

Commercial and Industrial temperature range

Available in 8-pin SOIC and TSSOP Packages

Applications

Product Description

The ASM3P28XX is targeted towards EMI management

for memory and LVDS interfaces in mobile graphic

chipsets and high-speed digital applications such as PC

peripheral devices, consumer electronics, and embedded

controller systems.

The ASM3P28XX devices are versatile spread spectrum

frequency modulators designed specifically for a wide

range of input clock frequencies from 10MHz to 40MHz.

Refer Input / Output Frequency Range Selection Table.

The ASM3P28XX can generate an EMI reduced clock

from crystal, ceramic resonator, or system clock. The

ASM3P28XX-A and the ASM3P28XX-B offer various

combinations of spread options and percentage

deviations. Refer Frequency Deviation and Spread

Selection Table. These combinations include Down
