without any skew on the clock) but for proper sampling of the data signals at the receiver side, the RGMII standard specifies that skew be added to the clock signal, either by the PCB traces, or internally by any of the MACs.ĭespite existing 2 independent clock paths it's necessary that both clocks run at the same frequency, for example 25Mhz for a 100Mbps link, or 125Mhz for a 1000Mbps link. The RGMII standard specifies that data and clock be output simultaneously (ie. This means that in RGMII there is no PHY or MAC role, so no special support is needed for MAC-to-MAC connection as it is the case, being both ends in RGMII mode is enough for the communication to be carried out. Our iMX6Qs Ethernet MAC is directly connected to the switchs port 5 MAC via RGMII with 6 nets in each direction: CLK, CTL and D 3:0. Plug the cable into a Internet at one end (this could be in a wall or a floor-mounted connection) Make sure the Internet is switched on Now connect the wire into the Ethernet port in your Mac Open a browser and test the connection.

We have a custom iMX6-based board which includes a Marvell 6350R switch. How to connect Mac to Ethernet If your Mac has an Ethernet port, then you need an Ethernet cable. Both paths have an independent clock, 4 data signals and a control signal. Direct MAC-MAC connection to Ethernet switch without a PHY. The Mac mini and 27-inch iMac both come with a 1G Ethernet port, but the M1 Mac mini can now be configured to 10 Gigabit for an additional 100.
The question is whether they have 1G or 10G Ethernet options.
The RGMII interface is a dual data rate (DDR) interface that consists of a transmit path and a receive path. All of Apple’s desktop Macs have Ethernet connections of some kind. There are variants of the MII (GMII RMII SGMII RGMII.) interface for connecting MACs to PHYs or MACs to MACs, in some of them there is a MAC or PHY role.
