Signal Description
GMII Transmit Clock (125MHz). This clock is used to synchronize the
transmit data.
MII transmit clock. Transmit data aligned to this clock input from
phy in MII mode. 25 Mhz in 100BaseT, 2.5 in Mhz in 10BaseT
Transmit Data (byte-wide data, least significant bit)
Transmit Data
Transmit Data
Transmit Data
Transmit Enable. When asserted, the data on TXD is encoded and
transmitted on the twisted pair cable.
nc
Collision. Asserted when both RX_DV and TX_EN are valid during
half duplex operation.
