Description
The RTL8306SD/RTL8306SDM supports two MII/RMII interfaces to work with various routing engines,
and one MII/RMII interface to work with HomePNA, HomePlug, or VDSL transceivers, as shown in
Figure 3, page 33.
The RTL8306SD/RTL8306SDM support a Dual MII/RMII interface for external devices to connect to
the 6th MAC, 5th MAC, and 5th PHY. The external device could be a routing engine, HomePNA,
HomePlug, or VDSL transceiver depending on the application.
The 5th PHY also supports external MII or RMII interface pins for connection to an external MAC.
Note: ‘MII/RMII 1’ signal pins are used only by MAC4. The ‘MII/RMII 2’ signal pins are used by PHY4
or MAC5.
