2.PRODUCT DESCRIPTION

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).

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. Not supported on WT-SFP-T.

 

4. 3.3V Volt 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 interface with no clocks.
