  • 2 - 0.7V current-mode differential CPU pairs
  • 6 - 0.7V current-mode differential SRC pairs
  • 2 - 0.7V current-mode differential ATIG pairs
  • 1 - HyperTransport clock seed
  • 2 - 48MHz USB clock
  • 3 - 14.318MHz Reference clock
  • CPU outputs cycle-to-cycle jitter < 85ps
  • SRC outputs cycle-to-cycle jitter < 125ps
  • ATIG outputs cycle-to-cycle jitter < 125ps
  • +/- 300ppm frequency accuracy on CPU, SRC & ATIG clocks
  • 3 - Programmable Clock Request pins for SRC and ATIG clocks
  • ATIGCLKs are programmable for frequency
  • Spread Spectrum for EMI reduction
  • Outputs may be disabled via SMBus
  • External crystal load capacitors for maximum frequency accuracy

    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
    • Document icon next to product name in row: View the featured document for this product
    • Chip icon next to the right of the document icon in row: View the block diagram for this product
    • Cart icon to the right of the chip icon: Indicates that samples are available for this product
