DUAL OUTPUT SPREAD SPECTRUM CLOCK SYNTHESIZER DATASHEET IDT6V40088 The IDT6V40088 is a low cost, dual-output clock synthesizer. The IDT6V40088 generates a 100 MHz and 27 MHz output from a 27 MHz crystal or clock input. The 100 MHz output may employ Spread Spectrum to reduce system electro-magnetic interference EMI . The device employs Phase-Locked Loop PLL techniques to run from a standard fundamental mode, inexpensive crystal, or clock. It can replace multiple crystals and oscillators, saving board space and cost. • 10-pin 3x3mm DFN package • Input crystal or clock frequency of 27 MHz • 32 kHz Spread Spectrum Modulation • Adjustable down spread • Operating voltage of V • Replaces multiple crystals and oscillators • Advanced, low-power CMOS process Block Diagram S0:S1 27 MHz Crystal or Clock input X1/ICLK Crystal Oscillator External capacitors are required. 100 MHz 27 MHz DUAL OUTPUT SPREAD SPECTRUM CLOCK SYNTHESIZER IDT6V40088 DUAL OUTPUT SPREAD SPECTRUM CLOCK SYNTHESIZER CLOCK SYNTHESIZER Pin Assignment X1/ICLK GND_27 S1 VDD_PLL 100M 1 10 29 38 47 56 X2 27M VDD_27 S0 GND_PLL 10-pin DFN 3x3mm 100 MHz Spread Selection Table S1 S0 Down Spread% LH ML MM MH HL HM HH Pin Descriptions Pin Number 1 2 3 4 5 6 7 8 9 10 11 Pin Name X1/ICLK GND_27 S1 VDD_PLL 100M GND_PLL S0 VDD_27 27M X2 GPAD Pin Type XI Power Input Power Output Power Input Power Output XO NC Pin Description Connect this pin to a 27 MHz crystal or external clock input. 27 MHz ground.
