Overview
The W42C31-09 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.

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 3.3V or 5V supply
• Low-power CMOS design
• Available in 8-pin SOIC (Small Outline Integrated Circuit)
