    KSZ9131RNXV-TRVAO

    The KSZ9131RNX is a completely integrated triple-speed (10BASE-T/100BASE-TX/1000BASE-T) Ethernet physicallayer transceiver for transmission and reception of data on standard CAT-5 as well as CAT-5e and CAT-6 unshielded
    twisted pair (UTP) cables.
    The KSZ9131RNX provides the Reduced Gigabit Media Independent Interface (RGMII) for direct connection to RGMII
    MACs in Gigabit Ethernet processors and switches for data transfer at 10/100/1000 Mbps.
    The KSZ9131RNX reduces board cost and simplifies board layout by using on-chip termination resistors for the four
    differential pairs and by integrating an LDO controller to drive a low-cost MOSFET to supply the 1.2V core.
    The KSZ9131RNX offers diagnostic features to facilitate system bring-up and debugging in production testing and in
    product deployment. Parametric NAND tree support enables fault detection between KSZ9131RNX I/Os and the board.
    The LinkMD® TDR-based cable diagnostic identifies faulty copper cabling. Remote, external, and local loopback functions verify analog and digital data paths.
    The KSZ9131RNX is available in a 48-pin, RoHS Compliant VQFN package. The AEC-Q100 automotive qualified parts,
    KSZ9131RNXU and KSZ9131RNXV, are available in a 48-pin RoHS compliant VQFN (wettable) package.
