DATASHEET 4 OUTPUT PCIE GEN1/2 SYNTHESIZER IDT5V41066 Recommended Applications Features/Benefits 4 Output synthesizer for PCIe Gen1/2 20-pin TSSOP package small board footprint Spread-spectrum capable reduces EMI General Description Outputs can be terminated to LVDS can drive a wider variety of devices The IDT5V41066 is a PCIe Gen2 compliant Power down pin greater system power management spread-spectrum-capable clock generator. The device has 4 differential HCSL outputs and can be used in OE control pin greater system power management communication or embedded systems to subtantially Spread% and frequency pin selection no software reduce electro-magnetic interference (EMI). The spread required to configure device amount and output frequency are selectable via select pins. Industrial temperature range available supports demanding embedded applications Output Features For PCIe Gen3 applications, see the 5V41236 4 - 0.7V current mode differential HCSL output pairs Key Specifications Cycle-to-cycle jitter < 100 ps Output-to-output skew < 50 ps PCIe Gen2 phase jitter < 3.0ps RMS Block Diagram VDD PD OE 2 Spread Spread Spectrum/ 3 Spectrum Output SEL 2:0 clock Circuitry selection CLKOUTA X1 CLKOUTA 25 MHz Clock CLKOUTB crystal or Oscillator PLL Clock CLKOUTB clock Synthesis X2 CLKOUTC CLKOUTC Optional tuning crystal CLKOUTD capacitors CLKOUTD 2 Rr(IREF) GND IDT 4 OUTPUT PCIE GEN1/2 SYNTHESIZER 1 IDT5V41066 REV D 112211IDT5V41066 4 OUTPUT PCIE GEN1/2 SYNTHESIZER Pin Assignment 1 20 CLKA VDDXD S0 2 19 CLKA S1 3 18 CLKB S2 4 17 CLKB X1 5 16 GNDODA X2 6 15 VDDODA PD 7 14 CLKC OE 8 13 CLKC GNDXD 9 12 CLKD IREF 10 11 CLKD 20-pin (173 mil) TSSOP Spread Spectrum Selection Table S2 S1 S0 Spread% Spread Type Output Frequency 0 0 0 -0.5 Down 100 0 0 1 -1.0 Down 100 0 1 0 -1.5 Down 100 0 1 1 No Spread Not Applicable 100 1 0 0 -0.5 Down 200 1 0 1 -1.0 Down 200 1 1 0 -1.5 Down 200 1 1 1 No Spread Not Applicable 200 IDT 4 OUTPUT PCIE GEN1/2 SYNTHESIZER 2 IDT5V41066 REV D 112211
