The Microchip Technology KSZ9031RNXIC is a completely integrated triple-speed (10Base-T/100Base-TX/1000Base-T) Ethernet physical-layer transceiver for transmission and reception of data on standard CAT-5 unshielded twisted pair (UTP) cable. It provides the reduced gigabit media independent interface (RGMII) for connection to RGMII MACs in Gigabit Ethernet processors and switches for data transfer at 1000Mbps or 10/100Mbps.

The KSZ9031RNXIC is a highly integrated device that includes all of the necessary components for a complete Ethernet physical layer, including:

• A physical medium attachment (PMA) sublayer that performs the electrical and optical signaling required to transmit and receive data over the Ethernet cable
• A media independent interface (MII) sublayer that provides a standardized interface between the physical layer and the media access control (MAC) layer
• A MAC address controller that stores the MAC address of the device and provides filtering of incoming packets
• A PHY control and status register interface that allows the MAC to control the operation of the PHY and monitor its status

The KSZ9031RNXIC also includes a number of features that make it ideal for a wide range of applications, including:

• Low power consumption: The KSZ9031RNXIC is designed to minimize power consumption in both active and power-down modes. This makes it ideal for battery-powered applications.
• Advanced power management features: The KSZ9031RNXIC includes a number of advanced power management features, such as wake-on-LAN and Energy Efficient Ethernet (EEE), which can further reduce power consumption in systems that are idle or have low traffic levels.
• Support for all Ethernet speeds: The KSZ9031RNXIC supports all three standard Ethernet speeds: 10Mbps, 100Mbps, and 1000Mbps. This makes it ideal for use in a wide range of networking applications.
• Easy to use: The KSZ9031RNXIC is easy to use and configure. It is fully compliant with the IEEE 802.3 Ethernet standard and includes a comprehensive set of documentation and support tools.

The KSZ9031RNXIC is available in a variety of package options, including a 48-pin quad flat pack (QFP) and a 32-pin thin quad flat pack (TQFP). It is also available in a lead-free version that is RoHS compliant.
