The 9FGV0841 is an 8-output very low power clock generator for PCIe Gen1–4 applications with integrated output terminations providing Zo=100 Ω. The device has 8 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.

Features

  • PCIe Gen1–4 compliant
  • Integrated terminations provide 100Ω differential Zo: reduced component count and board space
  • 1.8V operation: reduced power consumption
  • Outputs can optionally be supplied from any voltage between 1.05V and 1.8V: maximum power savings
  • OE# pins: support DIF power management
  • LP-HCSL differential clock outputs: reduced power and board space
  • 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 25MHz crystal; supports tight ppm with 0ppm synthesis error
  • Configuration can be accomplished with strapping pins: SMBus interface not required for device control
  • 3.3V tolerant SMBus interface works with legacy controllers
  • Space-saving 6 × 6 mm 48-VFQFPN; minimal board space
  • Selectable SMBus addresses: multiple devices can easily share an SMBus segment
  • Available in AEC-Q100 qualified, Grade 2 (-40°C to +105°C) version (wettable flank package)
