I have been searching on how to connect two Ethernet switch ICs together. I have designed a custom PCB. Beside some other features, it accommodates an Ethernet Switch IC. This works OK. The bandwidth I use is not more than 100 Mbps.
It is time now to expand Ethernet ports by connecting two Ethernet switch ICs together. They will be very close to each other, a few inches perhaps.
*IC's datasheet: RTL8306E*
I have walked through the datasheet but I am stuck at the 6th port.
RTL8306E has 6 ports. I use 5 ports of it as they have Rx+- and TX+- pins.
In order to connect to the other
RTL8306E Ethernet switch, I have only port 6 at hand. But this has different interface so called
And some configuration table from the datasheet:
Q1: Is it possible to use
MII interface between
RTL8306E Ethernet switch?
If so, how?
Q2: If not, can I turn port 6 MII interface into a regular port like the others on the IC? So it would be easier to connect it to any Ethernet switch either by magnetics or without magnetics or just capacitor coupling.
Since I am new to those, I like to hear your opinions and experiences.
Any input greatly appreciated.
