特性

  • Integrated terminations provide 100Ω differential Zo; reduced component count and board space
  • 1.8V operation; reduced power consumption
  • 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 are 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 is not required for device control
  • 3.3V tolerant SMBus interface works with legacy controllers
  • Space saving 5mm x 5mm 32-VFQFPN; minimal board space
  • Selectable SMBus addresses; multiple devices can easily share an SMBus segment

描述

The 9FGV0441 is a 4-output very-low power clock generator for PCIe Gen 1–4 applications with integrated output terminations providing Zo = 100Ω. The device has four output enables for clock management and supports two different spread spectrum levels in addition to spread off.
