DATASHEET 4 OUTPUT PCIE GEN1/2/3 SYNTHESIZER 5V41236 Recommended Applications Features/Benefits Four output synthesizer for PCIe Gen1/2/3 20-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 5V41236 is a PCIe Gen1/2/3 compliant spread Power-down pin greater system power management 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 substantially 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 Key Specifications Four 0.7V current mode differential HCSL output pairs Cycle-to-cycle jitter < 100ps Output-to-output skew < 50ps PCIe Gen2 phase jitter < 3.0ps RMS PCIe Gen3 phase jitter < 1.0ps 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 GEN1/2/3 SYNTHESIZER 1 5V41236 SEPTEMBER 18, 20195V41236 4 OUTPUT PCIE GEN1/2/3 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 GEN1/2/3 SYNTHESIZER 2 5V41236 SEPTEMBER 18, 2019
