Overview
10/100/1000 BASE-T Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA) . They are compatible with the Gigabit Ethernet standards as specified in IEEE Std 802.3 .The 10/100/1000 BASE-T physical layer IC (PHY) can be accessed via I2C, allowing access to all PHY settings and features.
10/100/1000 BASE-T is compatible with 1000BASE-X auto-negotiation, but does not have a link indication feature (RX_LOS is internally grounded).10/100/1000 BASE-T Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA) .

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.
3.3V Electrical Power Interface
The 10/100/1000 BASE-T has an input voltage range of 3.3 V +/- 5%. The 4V maximum voltage is not allowed for continuous operation.

Notes:
1. Clock tolerance is +/- 50 ppm
2. By default, 10/100/1000 BASE-T is a full duplex device in preferred master mode
3. Automatic crossover detection is enabled. External crossover cable is not required
4. 10/100/1000 BASE-T operation requires the host system to have an SGMII interfacewith no clocks.
