An ethernet PHY chip speed support

An ethernet PHY chip speed support

I found this ethernet PHY chip. The specifications say that the Physical Network Type is '10BASE-T' on the one hand, but on the other hand the data rate is '10 Mbit/s, 100 Mbit/s, 1000 Mbit/s'.
As far as I know, a 10BASE-T chip can not support a data rate of 1Gbit/s ! Moreover, the 10BASE-T doesn't support Full-duplex, but the specifications say that the Communication Mode is 'Full Duplex, Half Duplex'.
Please help me solve this contradiction. Thank you.
