Spread Spectrum Clock Generator


The ICS7152-12 is a clock generator for EMI (Electro Magnetic Interference) reduction. Spectral peaks can be attenuated by slightly modulating the oscillation frequency. Both down and center spread profiles are selectable. Center spread maintains an average frequency equal to an unspread clock. Down spread meets maximum frequency specs over the entire modualtion cycle.


  • Operating voltage of 3.3 V ±0.3 V
  • Packaged in 8-pin SOIC
  • Input frequency range of 16.6 to 134.0 MHz
  • Output frequency range of 16.6 to 134.0 MHz
  • Provides a spread spectrum clock output (±0.5%, ±1.5% center spread; -1.0%, -3.0% down spread)
  • Advanced, low-power CMOS process
  • Industrial temperature range available
  • Pb (lead) free package, RoHS compliant
