The 9FGV0641 is a member of IDT's SOC-Friendly 1.8V Very-Low-Power PCIe clock family. The device has integrated 100 ohm output terminations providing direction connection to 100 ohm transmission lines. The device also has 6 output enables for clock management and supports 2 different spread spectrum levels in addition to spread off.

For information regarding evaluation boards and material, please contact your local IDT sales representative.


  • PCIe Gen1–4 compliant
  • LP-HCSL outputs with integrated terminations; save 24 resistors compared to standard PCIe devices
  • 54 mW typical power consumption; reduced thermal concerns
  • Outputs can optionally be supplied from any voltage between 1.05 and 1.8V; maximum power savings
  • OE# pins; support DIF power management
  • Programmable slew rate for each output; allows tuning for various line lengths
  • Programmable output amplitude; allows tuning for various application environments
  • DIF outputs blocked until PLL is locked; clean system start-up
  • Selectable 0%, -0.25% or -0.5% spread on DIF outputs; reduces EMI
  • External 25 MHz crystal; supports tight ppm with 0 ppm synthesis error
  • Configuration can be accomplished with strapping pins; SMBus interface not required for device control
  • 3.3 V tolerant SMBus interface works with legacy controllers
  • Space saving 5x5 mm 40-pin VFQFPN; minimal board space
  • Selectable SMBus addresses; multiple devices can easily share an SMBus segment
