Overview
The W42C32-05M 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 harmonics. Since peak amplitudes are reduced, the radiated electromagnetic emissions of the W42C32-05M are significantly lower than the typical narrow band signal produced by oscillators and most frequency generators.

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
• Power-down mode reduces current consumption and disables the clock outputs
• Available in 16-pin SOIC package (300 mil)
