1. GENERAL DESCRIP
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 and 1000BASE-T standards as specified in IEEE Std 802.3 . The 1000 BASE-T physical layer IC (PHY) can be accessed via I2C, allowing access to all PHY settings and features.
It supports a SERDES, does not have a link indication feature，and 1000BASE-X auto-negotiation should be disabled on host system
2. Features
● Up to 1.25 Gb/s bi-directional data links
● Low power dissipation(1.05W typical)
● Compact RJ-45 connector assembly
● Fully metal enclosure, for lower EMI
● RoHS compliant and lead-free
● Single +3.3V power supply
● Case operating temperature：
Commercial: 0℃ to +70℃
Extended: -10℃ to +80℃
Industrial: -40℃ to +85℃

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
