Features

  • PCIe Gen 1–4 compliant
  • 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 4mm x 4mm 24-pin VFQFPN; minimal board space

Description

The 9FGV0241 is a 2-output very low power frequency generator for PCIe Gen 1–4 applications with integrated output terminations providing Zo = 100Ω. The device has two output enables for clock management and supports two different spread spectrum levels in addition to spread off.
