概要

The 8T49N004I is a four output Clock Generator with selectable LVDS or LVPECL outputs. The 8T49N004I can generate any one of four frequencies from a single crystal or reference clock. The four frequencies are selected from the Frequency Selection Table (Table 3A) and are programmed via I2C interface. The four predefined frequencies are selected in the user application by two frequency selection pins. Note the desired programmed frequencies must be used with the corresponding crystal as indicated in Table 3A. Excellent phase noise performance is maintained with Renesas' 4TH Generation FemtoClock™ NG PLL technology.

    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
