Laser Printer System Frequency Synthesizer


  • Maximized EMI suppression using Cypress’s Spread Spectrum technology
  • Reduces measured EMI by as much as 10 dB
  • Four skew-controlled copies of CPU output
  • Four skew-controlled copies of SDRAM output
  • One copy of 14.31818-MHz Reference output
  • One copy of 48-MHz USB clock (not spread)
  • Selectable SSFTG modulation width
  • Available in 28-pin SSOP (209 mil)

Spread Spectrum Generator

The device generates a clock that is frequency modulated in order to increase the bandwidth that it occupies. By increasing the bandwidth of the fundamental and its harmonics, the amplitudes of the radiated electromagnetic emissions are reduced.
