Rgmii mac to mac Isn't xMII used to connect PHY to MAC? How can ports 2 and 6, configured as PHY mode, still talk to external PHYs? -----'@idogan wrote: Hi, We also try to connect zynq 7045 gem0 RGMII MAC to marvell 88e6352 eth. If you are using the Ethernet FMC , the PHY is the Marvell 88E151x , and the Ethernet MAC is inside the FPGA. Most CPU cores include only an integrated MAC. The RGMII specification calls for CLK to be delayed from DATA at the receiver in either direction by a minimum 1. M93 RGMII to PHY connection, delay adding tips. MAC and PHY are external (see Figure 1-4). Most RGMII PHYs support delays within the PHY in order to meet the spec. We have a custom iMX6-based board which includes a Marvell 6350R switch. RGMII) with MCIMX6QP6AVT1AA. It also provide solution on Is it possible that the LAN7801 could be connected in MAC to MAC mode to Xilinx MPSoC which has an internal MAC unit with RGMII interface? Yes, this is possible. Any idea on how to connect the pins for MAC to MAC communication. So i'm not able to transmit to 1000Mbits. 5G Ethernet Subsystem IP support direct MAC-MAC communication?
