For those not well-versed in Ethernet physical layer (PHY) lingo, it can be overwhelming to evaluate the various types. The MII clocks run at 25 or 50MHz. 3z) interfaces. Close Filter Modal. i. The board has one Artix XC7A35 from Xilinx and a MII Ethernet interface. 1 10 of 60 Document ID 431: AUTOSAR_SWS_EthernetTransceiverDriver - AUTOSAR confidential - 3 Related documentation 3. Resource Library. Figure 1-1. External PHY registers are accessed via a specified MAC or a dedicated controller (e. Simulate, Compile, and Validate (MAC+PCS) - Single Instance 6. Ixiasoft. Interface Type = MII, RGMII, Most fast ethernet adapters use an MII to autonegotiate link speed and duplex setting. Timing Constraints 9. \$\begingroup\$ RMII is like RGMII only a DDR version of MII and GMII, respectively. Smart Filtering As you select one or more parametric filters below, Smart Filtering will instantly disable any unselected values that would cause no results to be found. e. Figure 2. Applied Filters: Semiconductors Communication & Networking ICs Ethernet ICs. The MII is standardized by IEEE 802. Software Programming Interface 11. 3 standards for the Media Independent Interface, or MII. 5G Ethernet PCS/PMA or SGMII AMD ® IP — Connect So, to address these issues and create this inherent flexible architecture, the “MII Extender concept, first introduced as part of the 10 Gigabit Ethernet standard, was adopted. Industry’s smallest form factor Reduces PCB space I2C, MII, RGMII, RMII, SGMII, SPI Ethernet Switches Ethernet-ICs sind bei Mouser Electronics erhältlich.
