Features

• Maximized EMI suppression using Cypress’s Spread Spectrum technology
• Generates a spread spectrum timing signal
• Reduces measured EMI by as much as 12 dB
• Integrated loop filter components
• Requires a single low-cost fundamental crystal (or other frequency reference) for proper operation
• Special spread spectrum control functions
• Low-power CMOS design
• Available in 16-pin SOIC package, (300 mil) Overview The W42C32 modulates the output of a single PLL in order to ‘spread’ the bandwidth of a synthesized clock and, more importantly, decrease the peak amplitudes of its fundamental harmo.
