The 9FGL0641/51 devices are 3.3V members of IDT's 3.3V Full-featured PCIe family. The devices have 6 output enables for clock management and support 2 different spread spectrum levels in addition to spread off. The 9FGL0641/51 supports PCIe Gen1–4 Common Clocked architectures (CC) and PCIe Separate Reference no-Spread (SRnS) and Separate Reference Independent Spread (SRIS) clocking architectures.
For information regarding evaluation boards and material, please contact your local IDT sales representative.


  • PCIe Gen1–4 CC-compliant
  • PCIe Gen2–3 SRIS-compliant
  • Supports PCIe SRnS clocking
  • Direct connection to 100Ω (xx41) or 85Ω (xx51) transmission lines saves up to 24 resistors
  • Pin-selectable SRnS, CC 0% and CC/SRIS -0.5% spread
  • SMBus-selectable CC/SRIS -0.25% spread
  • One 3.3V LVCMOS REF output with Wake-On-LAN (WOL) support
  • Easy AC-coupling to other logic families, see IDT application note AN-891.
  • Space saving 5 × 5 mm 40-VFQFPN
