IDT5V41066

4 OUTPUT PCIE GEN1/2 SYNTHESIZER DATASHEET IDT5V41066 Recommended Applications 4 Output synthesizer for PCIe Gen1/2 General Description The IDT5V41066 is a PCIe Gen2 compliant spread-spectrum-capable clock generator. The device has 4 differential HCSL outputs and can be used in communication or embedded systems to subtantially reduce electro-magnetic interference (EMI). The spread amount and output frequency are selectable via select pins. Output Features 4 - 0.7V current mode differential HCSL output pairs Features/Benefits 20-pin TSSOP package; small board footprint Spread-spectrum capable; reduces EMI Outputs can be terminated to LVDS; can drive a wider variety of devices Power down pin; greater system power management OE control pin; greater system power management Spread% and frequency pin selection; no software required to configure device Industrial temperature range available; supports demanding embedded applications For PCIe Gen3 applications, see the 5V41236 Key Specifications Cycle-to-cycle jitter < 100 ps Output-to-output skew < 50 ps PCIe Gen2 phase jitter < 3.0ps RMS Block Diagram 3 SEL[2:0] 25 MHz crystal or clock X1 X2 Optional tuning crystal capacitors Spread Spectrum/ Output clock selection Clock Oscillator VDD 2 PD OE Spread Spectrum Circuitry PLL Clock Synthesis 2 GND Rr(IREF) CLKOUTA CLKOUTA CLKOUTB CLKOUTB CLKOUTC CLKOUTC CLKOUTD CLKOUTD IDT® 4 OUTPUT PCIE GEN1/2 SYNTHESIZER 1 IDT5V41066 REV D 112211 IDT5V41066 4...
