PCS3P2005A

General Purpose Peak EMI

Reduction IC

Features

1x, LVCMOS Peak EMI Reduction

Input frequency:

10MHz - 30MHz @ 3.3V

30MHz - 100MHz @ 5V

Output frequency :

components that are traditionally required to pass EMI

regulations.

PCS3P2005A modulates the output of a 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.‟

10MHz - 30MHz @ 3.3V

30MHz - 100MHz @ 5V

Four different Frequency Deviation selection

Selectable spread options: Down Spread and Center

Spread

PCS3P2005A accepts an input from an external

reference clock and locks to a 1x modulated clock output.

Two logic pins S0 and D_C enable selecting one of the 4

different frequency deviations. Refer to the Deviation

Selection Table for more details. Frequency Range

Selection pin enables operation in one of the two

frequency ranges. PCS3P2005A operates over a supply

voltage range of 5V / 3.3V. PCS3P2005A is available in 8

Pin TSSOP and SOIC Packages, over Commercial and

Industrial temperature range.

8 Pin TSSOP, SOIC Package

Commercial and Industrial temperature range

Product Description

PCS3P2005A is a versatile, 3.3V/5V, 1x spread spectrum

frequency modulator designed to reduce electromagnetic

interference (EMI) at the clock source, allowing system

wide reduction of EMI of down stream clock and data

dependent signals. The device allows significant system

cost savings by reducing the number of circuit board

layers ferrite beads, shielding and other passive

Application

PCS3P2005A is targeted for use in a broad range of

notebook and desktop PCs and consumer electronic

applications.
