The 9DB401C is a DB400 Version 2.0 Yellow Cover part with PCI Express® support. It can be used in PC or embedded systems to provide outputs that have low cycle-to-cycle jitter (50 ps), low output-to-output skew (100 ps), and are PCI Express® gen 1 compliant. The 9DB401C supports a 1 to 4 output configuration, taking a spread or non spread differential HCSL input from a CK410(B) main clock such as 954101 and 932S401, or any other differential HCSL pair. 9DB401C can generate HCSL or LVDS outputs from 50 to 200 MHz in PLL mode or 0 to 400 MHz in bypass mode. There are two de-jittering modes available selectable through the HIGH_BW# input pin, high bandwidth mode provides de-jittering for spread inputs and low bandwidth mode provides extra de-jittering for non-spread inputs. The SRC_STOP#, PD#, and OE real-time input pins provide completely programmable power management control.

    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
