W42C31-03
Spread Spectrum Frequency Timing Generator
Features
• Maximized EMI suppression using Cypress’s Spread Spectrum technology
• Generates a spread spectrum copy of the provided input
• Integrated loop filter components • Operates with a 5V supply • Low power CMOS design • Available in 8-pin SOIC (Small Outline Integrated
Circuit)
Overview
The W42C31-03 incorporates the latest advances in PLL spread spectrum frequency synthesizer techniques. By frequency modulating the output with a low-frequency carrier, EMI is greatly reduced. Use of this technology allows systems to pass increasingly difficult EMI testing without resorting to costly shielding or redesign.
