Product Description
WIWAV’s WSF-GE-T 1000BASE-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 1000BASE-T physical layer IC (PHY) can be accessed via I2C, allowing access to all PHY settings and features.
The WSF-GE-T uses the RX_LOS pin for link indication, and 1000BASE-X auto-negotiation should be disabled on the host system.

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 2.5 V.

Notes:
1. Clock tolerance is +/- 50 ppm
2. By default, the WSF-GE-T is a full duplex device in preferred master mode
3. Automatic crossover detection is enabled. External crossover cable is not required
4. WSF-GE-T does not support SGMII .With a SERDES the module will operate at 1000BASE-T only
