CUDY 1.25G SFP-T to 10/100/1000 Mbps RJ45 Module

SM220 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 SM220 uses the SFP's RX_LOS pin for link indication. If pull up SFP's TX_DISABLE pin, IC be reset.
