Product Description

PCS3P6200A is a versatile spread spectrum modulator

designed specifically for a wide range of clock

frequencies. The device addresses the need of a low

EMI clock generator for use in display systems covering

wide choice of pixel frequencies.

PCS3P6200A

reduces

electromagnetic

interference

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

of EMI of all clock dependent signals. PCS3P6200A

allows significant system cost savings by reducing the

number of circuit board layers, ferrite beads, shielding

that are traditionally required to pass EMI regulations.

The Supply Voltage of the Device is 3.3V/2.5V. It has two

Spread Selection Pins, SS1% and SS2% to select among

the four possible deviation options. The Frequency

Deviation across the Frequency range remains within

±10% of the selected deviation. Refer to the Frequency

Deviation Selection Table for details

. The Device is

available in a 6 Pin TSOT-26 Package, over Commercial

and Industrial temperature range.

Application

PCS3P6200A is targeted for use in a broad range of

applications including Liquid Crystal and Plasma Displays
