W530-02
Frequency-multiplying, Peak-reducing
EMI Solution
Features
• Cypress PREMIS™ SMARTSPREAD™ family offering
• Generates an electromagnetic-interference
(EMI)-optimized clocking signal at the output
• Selectable frequency range and multiplication factor
• Single 1.25%, 2.5%, 5%, or 10%, down or center spread
output
• Integrated loop filter components
• Operates with a 3.3V or 5V supply
• Low-power CMOS design
• Higher drive strength, higher frequency support than
W530
• Available in 20-pin SSOP
