PCS3P7100A Custom Clock Generator for Display Systems Features • Custom Clock Generator for Display Systems • W ide Operating Frequency Range covering most of the pixel frequencies • Generates a low EMI 1x Output • 4 Spread Deviation selection options • Supply voltage : 3.3V ± 0.3V 2.5V ± 0.125V • Frequency range: 3.3V: 20 MHz-130 MHz 2.5V: 30 MHz-130 MHz • 6L-TSOT23 (6L- SOT26) package frequencies. The device addresses the need of a low EMI clock generator for use in display systems covering wide choice of pixel frequencies. PCS3P7100A reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of all clock dependent signals. PCS3P7100A 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%. Refer to the Spread Deviation Selection Table for details.The Device is available in 6L-TSOT23 Package. Product Description PCS3P7100A is a versatile spread spectrum modulator designed specifically for a wide range of clock Application PCS3P7100A is targeted for use in Display Systems.
