The DP83867 device is a robust, low power, fully-featured physical layer transceiver (PHY) with integrated physical medium dependent (PMD) sublayers to support 10BASE-Te, 100BASE-TX, and 1000BASE-T Ethernet protocols. The device is designed for easy implementation of 10-, 100-, 1000-Mbps Ethernet LANs. The device interfaces directly to twisted pair media via an external transformer. This device interfaces directly to the media access controller (MAC) layer through the IEEE 802.3 Standard Media Independent Interface (MII), the IEEE 802.3 Gigabit Media Independent Interface (GMII) or Reduced GMII (RGMII). This reference design used the RGMII interface for the connection between MAC and PHY.
