2.PRODUCT DESCRIPTION
SFP-T-AUTO Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA) . They are compatible with the Gigabit Ethernet and 10/100/1000BASE-T standards as specified in IEEE Std 802.3 .
The SFP-T-AUTO uses the SFP's RX_LOS pin for link indication. If pull up SFP's TX_DISABLE pin, PHY IC be reset.
