Product Description

The PI6CFGL601B is a 6-output low-power 100MHz clock sythesizer for PCIe Gen 1-2-3. It runs from a 25MHz XTAL, provides spread spectrum capability, and has an SMBus for software control of the device. 


  • 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 -0.5% and no spread
  • Programmable output amplitude
  • 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: 32-TQFN 


  • PCIe 3.0/2.0/1.0 clock generation
