MK1714-02
Spread Spectrum Multiplier Clock
Description
The MK1714-02 is a low cost, high performance
clock synthesizer with selectable multipliers and
spread amounts (percentages), 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 a
clock input to produce a spread, or dithered,
output, thereby reducing the frequency amplitude
peaks 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.
Features
• Packaged in 20 pin tiny SSOP (QSOP)
• Operating VDD 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 testing
• Power down pin stops the outputs low
• Selectable frequency spread
• Spread can be turned on or off
• Duty cycle of 40/60
• Advanced, low power CMOS process
• Industrial temperature range available

For S4:S0, 0 = connect to GND, 1 = connect to VDD.
Direction: C=Center spread, D=Down spread, DC=Down+Center spread.
Amount equals the spread amount. So for a 40 MHz output clock spread down 1%, the lowest
frequency is 39.60 MHz.
Contact ICS with your exact output frequency for details on spread direction and amount.
