Automotive Grade PCI Express (PCIe) Clock Buffers

Silicon Labs offers a portfolio of  automotive grade, AEC-Q100 PCI Express Gen1/2/3/4/5 compliant low-power fanout buffers ideally suited for infotainment, ADAS sensors, and automated driving platforms. These devices feature HCSL output drivers that can support both 85Ω and 100Ω impedance, and feature full internal termination to minimize external components and board space.  


  • Automotive Grade2, -40 to +105 °C
  • AEC-Q100 qualified
  • 4/8-Output options


  • Single or dual input options
  • Output driver impedance selection (85/100 Ω )
  • Hardware output enable pins
  • Low additive jitter: 50 fs rms (PCIe Gen4)
  • Integrated termination resistors
  • Excellent PSNR
