Spread Spectrum PLL

The IDT5P50901/2/3/4 is a family of 1.8V low power, spread spectrum clock generators capable of reducing EMI radiation from an input clock. Spread spectrum technique is capable of reducing the harmonic frequency amplitude peaks by several dB.


  • 8-pin DFN package (2x2mm)
  • 8-pin MSOP package (3x4.9mm)
  • Provides a spread spectrum output clock
  • Input frequency range of 10 to 25 MHz
  • Output frequency range of 10 to 25 MHz
  • Center and down spread
  • Peak reduction by 8 dB to 16 dB typical on 3rd through 19th odd harmonics
  • Low EMI feature can be disabled
  • Operating voltage of 1.8 V, 2.5 or 3.3V
  • RoHS 6 compliant package
