6-output 3.3 V PCIe Clock Generator

The 9FGL06 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 9FGL06 supports PCIe Gen1-4 Common Clocked architectures (CC) and PCIe Separate Reference no-Spread (SRnS)  and Separate Reference Independent Spread (SRIS) clocking architectures. The 9FGL06P1 can be programmed with a user-defined power up default SMBus configuration.
For information regarding evaluation boards and material, please contact your local IDT sales representative.


  • PCIe Gen1-2-3-4 CC-compliant
  • PCIe Gen2-3 SRIS-compliant
  • Supports PCIe SRnS clocking
  • Direct connection to 100Ω (xx41) or 85Ω (xx51) transmission lines; saves 24 resistors compared to standard PCIe devices
  • Pin/SMBus selectable 0%, -0.25% or -0.5% spread on DIF outputs; minimize EMI and phase jitter for each application
  • 1 - 3.3V LVCMOS REF output w/Wake-On-LAN (WOL) support
  • Easy AC-coupling to other logic families, see IDT application note AN-891.
  • Space saving 40-pin 5x5mm VFQFPN; minimal board space
