PCS3P8103A

General Purpose Peak EMI

Reduction IC

Features

• Generates a 4x low EMI spread spectrum clock

number of circuit board layers, ferrite beads, shielding,

and other passive components that are traditionally

required to pass EMI regulations.

• Input Frequency: 16.667MHz

• Output Frequency: 66.66MHz

• Tri-level frequency Deviation Selection:

• Down Spread, Center Spread and No Spread

• Low inherent Cycle-to-Cycle Jitter

• Supply Voltage: 3.3V±0.3V

The custom device can generate an EMI reduced clock

from crystal, or system clock.

The PCS3P8103A has a 3 level logic control SS% for

selecting Center Spread, Down Spread and No-Spread

options. Refer to Output Frequency Deviation table.

• LVCMOS Input and output

• 6L-TSOT-23 (6L-TSOT-26) Package

The PCS3P8103A operates from a 3.3V±0.3V supply

Voltage and is available in a 6L-TSOT-23 package.

Product Description

The PCS3P8103A is

a versatile spread spectrum

Application

frequency modulator designed specifically to provide a 4x

output of 66.66MHz from an input clock of 16.667MHz.

The PCS3P8103A is targeted towards EMI management

in applications such as LCD Panels, MFPs, Digital

copiers, Networking, PC peripheral devices, consumer

electronics, and embedded controller systems.

The PCS3P8103A reduces electromagnetic interference

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

of EMI of down stream clock and data dependent signals.

It allows significant system cost savings by reducing the
