Product Description

The PI6CEQ20200 is a high performance PCIe Gen2/ Gen3 zero delay buffer with two HCSL outputs. Diodes' proprietary equalization technique used in this device improves signal integrity and makes this device suitable for PCIe Gen2/ Gen3 applications even when the input from the main clock has to travel a long distance.


  • PCIe Gen2/ Gen3* compliant clock buffer/ZDB
    * Gen3 performance only available in Commercial temp
  • Internal equalization for better signal integrity
  • 2 HCSL outputs
  • Dual PLL bandwidth for SSC tracking
  • Cycle-to-Cycle Jitter : 40ps (typ)
  • Output-to-Output Skew <10ps
  • 3.3V supply voltage
  • TSSOP-20 packages


  • Servers
  • Embedded computing systems
  • Networking systems
