Spread Spectrum Multiplier Clock

The MK1714-02 is a low cost, high performance clock synthesizer with selectable multipliers and percentages of spread designed to generate high frequency clocks with low EMI. Using analog/digital Phase Locked Loop (PLL) techniques, the device accepts an inexpensive, fundamental mode, parallel resonant crystal or clock input to produce a spread or dithered output. This reduces the EMI amplitude peaks at the odd harmonics by several dB. The OE pin puts both outputs into a high impedance state for board level testing. The PD pin powers down the entire chip and the outputs are held low.


  • Packaged in 20-pin tiny SSOP
  • Pb (lead) free package
  • Operating voltage of 3.3 V or 5 V
  • Multiplier modes of x1, x2, x3, x4, x5, and x6
  • Inexpensive 10 - 25 MHz crystal or clock input
  • OE pin tri-states the outputs for board testing
  • Power down pin stops the outputs low
  • Selectable frequency spread
  • Spread can be turned on or off
  • Advanced, low power CMOS process
  • Duty cycle of 40/60
  • Industrial temperature range available
