Overview

The 843201-375 is a low phase-noise frequency margining synthesizer. In the default mode, the device nominally generates a 375MHz LVPECL output clock signal from a 25MHz crystal input. There is also a frequency margining mode available where the device can be configured, using control pins, to vary the output frequency up or down from nominal by 5%. The 843201-375 is provided in a 16-pin TSSOP package.

    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
