ASM3P2811A/B and ASM3P2812A/B and ASM3P2814A/B

Low Power EMI Reduction IC

Features

• FCC approved method of EMI attenuation

• Provides up to 15dB EMI reduction

combinations of spread options and percentage

deviations. Refer to Frequency Deviation and Spread

Selection Table. These combinations include Down and

Center Spread, and percentage deviation range from

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

clock of the input frequency

±0.625% to -3.5%.

o 1x: ASM3P2811A/B

The ASM3P28XX reduces electromagnetic interference

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

of EMI of downstream 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.

o 2x: ASM3P2812A/B

o 4x: ASM3P2814A/B

• Optimized for input frequency range from 10MHz to

40MHz

• Internal loop filter minimizes external components

and board space

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’.

• Selectable spread options:

o Down Spread and Center Spread

• 8 frequency deviation selections:

o ±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.

• Available in 8-pin SOIC and TSSOP Packages

Product Description

Applications

The ASM3P28XX devices are versatile spread spectrum

frequency modulators designed specifically for a wide

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

Refer to 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

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.
