概要

The 9FGV0431 is a 4-output very-low power clock generator for PCIe Gen 1–4 applications. The device has four output enables for clock management and supports two different spread spectrum levels in addition to spread off.

  • 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

    Parametric Table tips

    Tips for Using This Parametric Table:

    • Hide Filters button in header: Collapse or expands filters
    • Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
    • Reset button in header: Reset all filters to the page default
    • Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
    • Export button in header: Export the filtered results of the table to an Excel document
    • Filter parts search bar in header: Type to filter table results by part number
    • Hide column button in column headers: Select to hide columns in table
    • AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
    • Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
