I just cant sleep till i make this thing clear. We have a 10/100 Mb/s NIC which transmits 33 000 000 Hz x 32 Bytes width = 132 MB/s over PCI 2.2 But how do you guys count 12.5 MB/s in the cable when the NIC has lets say realtek 8139 25 MHz external clock. and 4 cables to transmit bi-directional data that is only TX+ TX- RX+ RX- which is only 2 bits long at a time so 25 MHz x 2 = 6.25 MB/s for 4 wires and 25 MHz x 4 = 12.5 MB/s for 8 wires. and how do you get 25 MB/s on a 1G link when the clock is still 25 MHz?
