MK1714-02 Datasheet | Renesas

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 d B. 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 PLL Clock Multiplier and Spread Spectrum Circuitry Clock Out REF OE (both outputs) IDT™ SPREAD SPECTRUM MULTIPLIER CLOCK MK1714-02 REV K 051310 MK1714-02 SPREAD SPECTRUM MULTIPLIER CLOCK SSCG Pin Assignment X2 X1/ICLK...
