MAC Data Interface
Transmit Data Bus. The width of this synchronous input bus varies with the speed/
mode:
1000: All 8 bits are used.
100 or 10 MII: TXD<3:0> are used; TXD<7:4> are ignored.
10 Serial: TXD<0> is monitored; TXD<7:1> are ignored.
Transmit Enable. This synchronous input indicates that valid data is being driven on
the TXD bus.
Transmit Clock. All transmit inputs must be synchronized to this output clock during
10/100 operation. It is provided as a utility clock during 1000 operation. Its frequency
depends on the link speed/mode:
100/1000 Mbps: 25 MHz
10 MII and Auto-negotiation: 2.5 MHz
10 Serial: 10 MHz
Gigabit Transmit Clock. 125 MHz input clock; all transmit inputs must be
synchronized to this clock during 1000 operation.
Transmit Coding Error. This synchronous input causes the transmission of error
symbols in 1000/100 links. For half-duplex 1000 links, it will cause the generation of
carrier-extension symbols when properly synchronized with TX_EN (refer to 1000
Mbps operation section).
