EMI clock generator for use in display systems covering wide choice of pixel frequencies. PCS3P7100A of EMI of reduces electromagnetic interference
Custom Clock Generator for Display Systems Wide 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
(EMI) at the clock source, allowing system wide reduction 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 6 Pin TSOT-26 Package, in Commercial and Industrial Temperature grade.
