概要

The RC19020 is a 20-output PCIe Gen7 buffer that is backward compatible with earlier PCIe generations. The RC19020 provides ultra-low additive jitter and reduced in-to-out delay performance for better design margin and incorporates several features for easier and more robust design.

RC19020 is also pin-compatible to DB2000Q/DB2000QL plus adding Loss-Of-Signal (LOS) indication and an SBI_OUT pin for multiple clock chip daisy-chain.

    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
