概要

The 1893BF is a low-power, physical-layer device (PHY) that supports the ISO/IEC 10Base-T and 100Base-TX Carrier-Sense Multiple Access/Collision Detection (CSMA/CD) Ethernet standards, ISO/IEC 8802-3.

The 1893BF is intended for MII, node applications that require the Auto-MDIX feature that automatically corrects crossover errors in plant wiring.

The 1893BF incorporates Digital-Signal Processing (DSP) control in its Physical-Medium Dependent (PMD) sublayer. As a result, it can transmit and receive data on Unshielded Twisted-Pair (UTP) Category 5 cables with attenuation in excess of 24dB at 100MHz. With this patented technology, the 1893BF can virtually eliminate errors from killer packets.

The 1893BF provides a Serial-Management Interface for exchanging command and status information with a Station-Management (STA) entity. The 1893BF Media-Dependent Interface (MDI) can be configured to provide either half- or full-duplex operation at data rates of 10Mb/s or 100Mb/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
