    KSZ9031RNXIA Typical application Circuitry


    The KSZ9031RNXIA is a Gigabit Ethernet transceiver from Microchip. It is designed to provide physical layer (PHY) solutions for Ethernet applications. 

    Below is a general outline of a typical application circuit for this IC:

    1. Power Supply: The KSZ9031RNXIA IC requires different supply voltages for different sections: EDDA_25 for the 2.5V analog supply, EDDA_10 for the 1.0V analog supply, and VDD_33 for the 3.3V digital supply. Each supply pin should be decoupled with appropriate capacitors.

    2. Ethernet Interface: The KSZ9031RNXIA IC supports Reduced Gigabit Media Independent Interface (REMIX) for data communication. The REMIX interface typically includes data lines (RXD[3:0] and TXD[3:0]), control lines (RX_CTV, TX_CTV), and clock lines (RX_ELK, TX_ELK). These lines should be connected to your Ethernet MAC (Media Access Control).

    3. LED Indicators: The KSZ9031RNXIA IC has pinouts (LED[2:0]) for LED indicators to show link status, activity, speed, etc.

    4. MDC and MDI: These are management data clock and data IO, respectively, used for the management interface. They are used to configuring and managing the PHY.

    5. Clock Input/Output: The KSZ9031RNXIA IC has a 25MHz crystal input (CTI and TO) to generate a clock. It also includes a synchronous clock output (CLK125) for synchronous Ethernet applications.

    6. Reset: The nest (reset) pin is used to reset the IC. It is typically connected to a reset signal from your system or a reset circuit. Please note, that the details provided here are just a general guide.

    The exact application circuit will depend on your particular requirements and the overall system design. Always refer to the datasheet of the KSZ9031RNXIA and relevant application notes provided by Microchip for the most accurate and reliable information.
