Product Description

The PI6CFGL201B is a 2-output very low power 100MHz fre- quency generator for PCIe Gen 1, 2 and 3 applications with inte- grated output terminations providing Zo=100Ω. The device has 2 output enables for clock management and supports 2 different spread spectrum levels in addtion to spread off. The device also has one 1.8V LVCMOS REF1.8 output.


  • 25MHz crystal or reference clock input
  • 100MHz low power HCSL or LVDS compatible outputs
  • PCIe 3.0, 2.0 and 1.0 compliant
  • Selectable spread spectrum of -0.25%, -0.5% and no spread
  • Programmable output amplitude and slew rate
  • Cycle-to-cycle jitter (typ.) ~ 30ps
  • Supply voltage of 3.3V+/-10%
  • Output supply voltage of 1.8V
  • Industrial ambient operating temperature
  • Available in lead-free package: 24-TQFN


  • PCIe 3.0/2.0/1.0 clock generation
