Overview

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 • 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 Block Diagram 5 S4:0 PD Low EMI Enable X1 Input Crystal or Clock X2 Crystal Oscillator XSEL VDD 2 PLL Clock Multiplier and Spread Spectrum Circuitry Clock Out REF 4 GND OE (both outputs) IDT™ SPREAD SPECTRUM MULTIPLIER CLOCK 1 MK1714-02 REV K 051310 MK1714-02 SPREAD SPECTRUM MULTIPLIER CLOCK SSCG Pin Assignment X2 1 X1/ICLK 2 VDD 3 VDD 4 S4 5 S3 6 GND 7 GND 8 S2 9 CLK 10 20 REF 19 OE 18 PD 17 GND 16 S0 15 NC 14 S1 13 GND 12 LEE 11 XSEL 20 pin (150 mil) SSOP (QSOP) Pin Descriptions Pin Pin Pin Number Name Type Pin Description 1 X2 XO Crystal connection.
