KSZ8895MQ/RQ/FMQ
MII Interface Operation
The media-independent interface (MII) is specified by the IEEE 802.3 committee and provides a common interface
between physical layer and MAC layer devices. The KSZ8895MQ/RQ/FMQ provides two such interfaces. The P5-MII
interface is used to connect to the fifth PHY, where as the SW-MII interface is used to connect to the fifth MAC. Each
of these MII interfaces contains two distinct groups of signals, one for transmission and the other for receiving.
Port 5 PHY 5 P5-MII/RMII Interface
The media independent interface (MII) is specified by the IEEE 802.3 committee and provides a common interface
between the physical layer and MAC layer devices. The Reduced Media Independent Interface (RMII) specifies a low
pin count MII. The KSZ8895MQ/RQ/FMQ provides two such interfaces for MAC5 and PHY5. The Port 5 PHY5 P5-
MII/RMII interface is used to connect to the fifth PHY, where as the SW-MII/RMII interface is used to connect to the
fifth MAC. The KSZ8895MQ/FMQ support P5-MII, the KSZ8895RQ supports P5-RMII. Each of these MII/RMII
interfaces contains two distinct groups of signals, one for transmission and the other for receiving. Table 3 describes
the signals used in the PHY[5] P5-MII/RMII interface. The P5-MII interface operates in PHY mode only.
