SPREAD SPECTRUM MULTIPLIER CLOCK

DATASHEET

MK1714-02

Description

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.

Features

• Packaged in 20-pin tiny SSOP

• Available in 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

NOTE: EOL for non-green parts to occur on 5/13/10

per PDN U-09-01
