Digital Semiconductor. ™. 2. Scope. ? Why Gigabit MII. ? MII in the layers model and the defined interface for. 10/100 Mb/s (802.3u). ? Gigabit MII proposal Digital Semiconductor. ™. 4. Why MII? ? Two device - MAC and PHY - implementations. – MAC and PHY technologies may be different. – Vendors expertise.
2 Jan 2008 Media Independent Interface: Standard 4-bit interface between the MAC and the PHY for communicating TX and RX frame data. In 10 Mb/s mode, the MII runs at 2.5 MHz; in. 100 Mb/s mode, it runs at 25 MHz. MIIM. MII Management: Set of MII sideband signals used for accessing the PHY registers. Ethernet
30 Jun 2011 Can any1 give me some details about the mii, rmii and smii interface. MII stands for Media Independent Interface (in your case). Similarly, RMII stands for Reduced Media Independent Interface and SMII for Serial Gigabit Media Independent Interface (SGMII is actually called).
Both EMAC ports on the TCI6486/C6472 device and the MDIO interface can be configured to use HSTL levels and be compatible with RGMII v2.0. Alternately, these modules can be configured to use separate pins that support 3.3-V LVCMOS I/O through the interface modes GMII, MII, RMII, or S3MII. Only one mode can be
The MII Status Word is the most useful datum, since it may be used to detect whether an Ethernet NIC is connected to a network. It contains a bitmask with the following meaning: 0x8000 Capable of 100baseT4 0x7800 Capable of 10/100 HD/FD (most common) 0x0040 Preamble suppression
6 Jun 2005 Hardware. This section goes deeper in the Physical and Data. Link layer of the OSI model. It also describes the. RJ45 jack, Magnetic, Power over Ethernet (PoE), and Media Independent Interface (MII) interface. All frequencies are shown in detail to provide the reader with a feeling of the signal chain in the.
Let me try to explain: (1)The MII, SGMII, RGMII are three kinds of interface between the MAC chip and the PHY chip. The Intel 82574L is one MAC chip. Looking following figure: ______ ______ ______ CPU | PCI-E | | MII/SGMII/RGMII | | or |<=======>| MAC |<================>| PHY
Ethernet frames recognizable and manageable by the SONET equipment they pass through. 10GBase Interfaces. Just as Fast Ethernet and Gigabit Ethernet have multiple interfaces, 10 Gigabit Ethernet has seven interfaces referred to in Table 2. Table 2: 10GBASE-x Interfaces. Interface. PHY. Optics. 10GBASE-SR. LAN.
