What is Rgmii interface?

What is Rgmii interface?

The RGMII interface is the physical connection between the Ethernet PHY and the Ethernet MAC. The RGMII interface is a dual data rate (DDR) interface that consists of a transmit path, from FPGA to PHY, and a receive path, from PHY to FPGA. Both paths have an independent clock, 4 data signals and a control signal.

What is Xlaui interface?

From Wikipedia, the free encyclopedia. 10 Gigabit Attachment Unit Interface (XAUI /ˈzaʊi/ ZOW-ee) is a standard for extending the XGMII (10 Gigabit Media Independent Interface) between the MAC and PHY layer of 10 Gigabit Ethernet (10GbE) defined in Clause 47 of the IEEE 802.3 standard.

What is MII and Rgmii?

The Media Independent Interface (MII) is a standard interface used to connect a Fast Ethernet (i.e. 100Mb/s) MAC-block to a PHY. Reduced Gigabit Media Independent Interface (RGMII) specifies a particular interface between an Ethernet MAC and PHY. RGMII uses half the number of pins as used in the GMII interface.

What is 40GBase KR4?

The 40GBase-KR4/CR4/SR4/LR4/KR2 Ethernet Verification IP is compliant with IEEE 802.3ba specifications and verifies MAC-to-PHY layer interfaces of designs with a 10G Ethernet interface 40GBase-KR4/CR4/SR4/LR4/KR2. It can work with SystemVerilog, Vera, SystemC, E and Verilog HDL environment.

What is a QSFP28 transceiver?

QSFP28 is a hot-pluggable transceiver module designed for 100G data rate. QSFP28 integrates 4 transmit and 4 receiver channels. “28” means each lane carries up to 28G data rate. QSFP28 can do 4x25G breakout connection, 2x50G breakout, or 1x100G depending on the transceiver used.

How is the Attachment Unit Interface ( AUI ) defined?

The Attachment Unit Interface (AUI) is a physical and logical interface defined in the original IEEE 802.3 standard for 10BASE5 Ethernet. The (optional) physical interface consists of a 15-pin connection that provides a path between an Ethernet node’s Physical Signaling and the Medium Attachment Unit (MAU), sometimes also known as a transceiver.

What does AUI stand for in Ethernet standards?

AUI stands for Attachment Unit Interface. AUI is a portion of Ethernet standards that specifies how a cable is going to connect to an Ethernet card. AUI is a physical and logical interface. AUI is defined in IEEE 802.3 standard for 10BASE5 Ethernet.

What kind of connector is the AUI connector?

AUI connector is a 15 port coonector that provides a path between an Ethernet node’s Physical Signaling and the Medium Attachment Unit (MAU). Attention reader!

Is the XGMII the same as the XAUI?

The XGMII is a 74 signal wide interface (32-bit data paths for each of transmit and receive) that may be used to attach the Ethernet MAC to its PHY. The XAUI may be used in place of, or to extend, the XGMII in chip-to-chip applications typical of most Ethernet MAC to PHY interconnects (See Figure 2).

What is Rgmii interface? The RGMII interface is the physical connection between the Ethernet PHY and the Ethernet MAC. The RGMII interface is a dual data rate (DDR) interface that consists of a transmit path, from FPGA to PHY, and a receive path, from PHY to FPGA. Both paths have an independent clock, 4 data…
