概要

The 7290820 is a non-blocking digital switch that has a capacity of 2,048 x 2,048 channels at a serial bit rate of 8.192Mb/s, 1,024 x 1,024 channels at 4.096Mb/s, and 512 x 512 channels at 2.048Mb/s. Some of the main features include programmable stream and channel control, Processor mode, input offset delay, and high-impedance output control.

Per-stream input delay control is provided for managing large multi-chip switches that transport both voice channels and concatenated data channels. In addition, input streams can be individually calibrated for input frame offset.

The device is an ST-BUS® compatible digital switch controlled by a microprocessor that can handle from 128 x 128 to 32K x 32K inputs to multiple outputs.

  • 2,048 x 2,048 channel non-blocking switching at 8.192Mb/s
  • Per-channel variable or constant throughput delay
  • Automatic identification of ST-BUS®/GCI interfaces
  • Accept streams of 2.048Mb/s, 4.096Mb/s or 8.192Mb/s

    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
