MII collision signal, provided by Ethernet PHY. This
I
signal is high when a collision is detected on the media.
MII carrier sense signal, provided by Ethernet PHY. This
I
signal is high if the media is not idle.
MII receive data valid indication, active high, sampled by
I
the rising edge of RX_CLKI
MII receive data input, sampled synchronously with the
I
rising edge of RX_CLKI
MII receiving clock, provided by Ethernet PHY. The
I
clock frequency is 2.5MHz or 25MHz
Power 2.5V
Power Ground
MII transmitting clock, provided by Ethernet PHY. The
