ASM3P5811B

The ASM3P5811B reduces electromagnetic interference

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

of EMI of down stream clock and data dependent

signals. The ASM3P5811B 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.

Features

ꢀ

FCC approved method of EMI attenuation.

Generates a 1X low EMI spread spectrum clock of

the input frequency.

ꢀ

Input frequency range: 10MHz – 20MHz.

Internal loop filter minimizes external components

and board space.

ꢀ

Frequency deviation: -2.5%

The ASM3P5811B uses the most efficient and optimized

modulation profile approved by the FCC and is

implemented in a proprietary all digital method.

Low inherent cycle-to-cycle jitter.

3.3V operating voltage.

TTL or CMOS compatible inputs and outputs.

Ultra-low power CMOS design.

The ASM3P5811B 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’.

TBD mA @ 3.3V, 16.6MHz

ꢀ

Pinout compatible with Cypress CY25811.

Products are available for industrial temperature

range.

ꢀ

Available in 8-pin SOIC and TSSOP.

Product Description

The ASM3P5811B is

a versatile spread spectrum

frequency modulator designed specifically for input clock

frequencies in the range of 10MHz - 20MHz. The

ASM3P5811B can generate an EMI reduced clock from

crystal, ceramic resonator, or system clock. The

ASM3P5811B offers a percentage deviation of –2.5%.

Applications

The ASM3P5811B is targeted towards EMI management

for high speed digital applications such as PC peripheral

devices, consumer electronics and embedded controller

systems.
