Product Description

The PI6PCIEB24 is a PCI Express® (PCIe) 2.0 compliant high-speed, low-noise differential clock buffer. The device distributes the input differential PCIe clock to four differential pairs of clock outputs with zero delay PLL.


  • Phase jitter filter for PCIe® 2.0 application
  • Four pairs of HCSL PCIe 2.0 Differential Clocks
  • Prop delay <± 250ps (in PLL mode)
  • Low skew < 50ps
  • Low jitter < 50ps cycle-to-cycle
  • < 1 ps additive RMS phase jitter
  • 100 MHz PLL Mode operation
  • 3.3V operation
  • Packaging (Pb-free and Green):
    - 20-Pin 4.0mm x 4.0mm x0.75mm TQFN (ZD20)
