This core is implemented in both Altera Cyclone-III and Xilinx Virtex-4 FPGA. : Text in black is generic and for inclusion in all final versions of Interface Specification documents. Today, we got a little more information with a product brief including the main features, and a block diagram.

Hi Antoine, I had a look at your patch. The Reduced Gigabit Media Independent Interface or RGMII is an low pin count interface between the PHY chip and the controller. The component is compliant with IEEE 802. 8V 45 GND ground NA NA 46 RGMII_MDC RGMII Interface Output 1. In case of RGMII, ‘EVMPortRGMIIModeSelect()’ can be used to enable RGMII mode in the chip configuration Reset the CPSW hardware. The parallel interface can be configured for GMII, RGMII, TBI, RTBI, or 10/100 MII, while the serial interface can be configured for 1. specifications. Ethernet protocol is instinctivly a Full-Duplex non-synced protocol, thus the TX and RX signals are completely independent. PHY register access is provided by a MIIM interface. With the inclusion of the MDIO/MDC serial management signals, the RTBI will not require independent control signals. An MDIO interface is supported for PHY management. The RGMII specification requires that the signal clock be delayed by 1/2 bit time (2ns) at the receiving end of the data path. The RGMII clock timing can be adjusted to eliminate the board trace delays required by the RGMII specification. Does this dev board has an RGMII interface that i can use to communicate with an external gigabit etherent transciever? or is the RMII interface only connected to an IC on the board? Question relating to:. And also one ethernet device driver should work with the NIC hardware. The Reduced Gigabit Media Independent Interface or RGMII is an low pin count interface between the PHY chip and the controller. Features • Supports up to 500 Mbps PHY rates over power line. Reduced Gigabit Media Independent Interface (RGMII) specifies a particular interface between an Ethernet MAC and PHY. Data transfer between MAC and PHY is via the Reduced Gigabit Media Independent Interface (RGMII) for 1000Base-T, 10Base-T, and 100Base-TX. The Reduced Gigabit Media Independent Interface (RGMII) is an alternative to the GMII. The RGMII interface has been designed in accordance with the standards and specifications agreed in the Hewlett Packard document Reduced Gigabit Media Independent Interface (RGMII) Specifications. Today, we got a little more information with a product brief including the main features, and a block diagram. 3z Interim, January 1997 GMII Electrical Specification - Goals Compatibility with ANSI TR/X3. These voltage levels are sele cted by connnecting the VDDIO MAC voltage pins. The KSZ9031RNX provides the Reduced Gigabit Media Independent Interface (RGMII) for direct connection to RGMII MACs in Gigabit Ethernet Processors and Switches for data transfer at 10/100/1000 Mbps speed. RGMII is an alternative to the IEEE 802. Data on the interface is framed using the IEEE Ethernet. As noted earlier, the external PHY transmits and receives data through the RGMII interface, but it is configured through the dedicated and standardized MDIO interface. iW-RainboW-G15D is a multipurpose platform powered by automotive grade i. Try to use via as less as possible on RGMII interface traces to minimize the timing skew. No change in the operation of the core is required to. 5 V Reduced Gigabit Media Independent Interface (RGMII) 2. Applications: Network Interface Adapter, MAU (Media Access Unit), CNR (Communication and Network Riser), ACR (Advanced Communication Riser), Ethernet hub, and Ethernet switch. The Marvell 88E1510 PHYs support the 1000BASE-T, 100BASE-TX, and 10BASE-T standards. And also one ethernet device driver should work with the NIC hardware. The KSZ9021RL provides the Reduced Gigabit Media Independent Interface (RGMII) for direct connection to RGMII MACs in Gigabit Ethernet Processors and Switches for data transfer at 10/100/1000Mbps speed.
