I am looking today at the different ways to connect a MAC with a PHY. I found a lot of things, which I summarise here:
Protocol --- Eth. Speed --- Signale --- Clock speed MII --- 10/100 --- 16 --- 2,5 / 25 MHz RMII --- 10/100 --- 6 / 7 --- 5 / 50 MHz SMII --- 10/100 --- 4 --- 125 MHz GMII --- 10/100/1000 --- 27 --- 125 MHz RGMII --- 10/100/1000 --- 12 --- 2,5 / 25 / 125 MHz SGMII --- 10/100/1000 --- 4 diff.pairs --- 625 MHz (clk) / 1,25 GHz (data)
Unfortunatly, I am missing infos about the Ten Bit Interfaces TBI and RTBI. According to a paper from HP
I didn't found any specs fot TBI oder RTBI on the net. Does anyone know more about them?
have a nice week-end :-) Francis
