MK1714-01 Spread Spectrum Multiplier Clock
MK1714-01 cost, high performance clock synthesizer with selectable multipliers percentages spread designed generate high frequency clocks with EMI. Using analog/digital Phase-Locked Loop (PLL) techniques, device accepts inexpensive, fundamental mode, parallel resonant crystal, clock input produce spread, dithered, output, thereby reducing amplitude peaks harmonics several puts both outputs into high impedance state board level testing. powers down entire chip, outputs held low.
Packaged tiny SSOP (QSOP) Operating 3.3V Multiplier modes Inexpensive 10-25 crystal, clock input tri-states outputs testing Power down stops outputs Selectable frequency spread Spread turned Duty cycle 40/60 Advanced, power CMOS process also MK1714-02 more selections input ranges spreads

Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage device. Prolonged exposure levels above operating limits below Absolute Maximums affect device reliability. With clocks highest frequencies.
External Components
MK1714 requires minimum number external components proper operation. Decoupling capacitors 0.01µF should connected between pins close chip possible. series termination resistor used each clock output. crystal must connected close chip possible. crystal should fundamental mode parallel resonant. accurate tuning required, crystal capacitors should connected from pins ground ground. value these capacitors given following equation, where crystal load capacitance: Crystal caps (pF) crystal with 20pF load capacitance, caps should used. clock input used, drive into leave unconnected.
