  • Page 5: Introduction

    Ethernet Physical Layer Transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable. The KSZ9031RNX reduces board cost and simplifies board layout by using on-chip termination resistors for the four differential pairs and by integrating a LDO controller to drive a low cost MOSFET to supply the 1.2V core.

  • Page 6: Hardware Description

    RGMII loop back path can be opened to allow the RGMII signals to be wired to a Gigabit MAC on another board. The KSZ9031RNX-EVAL board receives power from a DC power jack (J13). Any DC power adapter in the range of 5V to 12V with a current rating of 2 Amp or better can be used.
