Bascom Ave Suite 200, Campbell, CA 95008 • Tel: 408-879-9077 • Fax: 408-879-9018 www.pulsecoresemi.com Spread Spectrum Clock Generator Features • Generates a 4X low EMI spread spectrum clock of the input frequency. • Input frequency: 10MHz - 25MHz • Output frequency: 40MHz - 100MHz • Internal loop filter minimizes external components and board space. • Selectable Centre Spread frequency deviation: ±0.5%, ± 1.0%, ± 1.5%, ± 2.0% • Supply Voltage :3.3V ± 0.3V • Commercial and Industrial temperature range • 8-pin TSSOP Package • Low power CMOS process Product Description PCS3P2189A is a versatile spread spectrum frequency modulator that generates a low EMI 4x clock at the output. PCS3P2189A offers four selectable centre spread options of ±0.5%,±1.0%,±1.5%,±2.0%,(Refer Spread Deviation Selection Tabnle). PCS3P2189A reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of all clock dependent signals. The PCS3P2189A allows significant system cost savings by reducing the number of circuit board layers, ferrite beads, and shielding that are traditionally required to pass EMI regulations. PCS3P2189A has spread spectrum ON/OFF option. The PCS3P2189A uses the most efficient and optimized modulation profile approved by the FCC and is implemented in a proprietary all digital method. Application PCS3P2189A is targetted for LCD panel application Block Diagram ModOUT CLKIN / XIN VSS Frequency Divider Feedback Divider Modulation Phase Detector Loop Filter VCO Output Divider PLL VDD XOUT Crystal Oscillator S0 SSON S1 |
