Notes:
1. Circuit ground is connected to chassis ground
2. Should be pulled up with 4.7k - 10k Ohms on host board to a voltage between 2.0 V and 3.6 V. MOD_DEF(0) pulls line low to indicate module is plugged in.
3. LVTTL compatible with a maximum voltage of 2.5V.
3.+3.3V Volt ElECTRICAL POWER INTERFACE
The 1000base-T has an input voltage range of 3.3 V +/- 5%. The 4V maximum voltage is not allowed for continuous operation.

2. By default, the 1000BASE-T is a full duplex device in preferred master mode
3. Automatic crossover detection is enabled. External crossover cable is not required
4. 1000BASE-T does not support SGMII .With a SERDES the module will operate at 1000 BASE-T only
