LCP-1250RJ3SR

LCP-1250RJ3SR-S RoHS Compliant Copper Small Form-factor Pluggable (SFP) Transceiver for Gigabit Ethernet with SGMII Interface Features Compatible with specifications for IEEE 802.3z/Gigabit Ethernet Compliant with MSA specifications for Small Form Factor Pluggable (SFP) Ports Hot-Pluggable SFP footprint Compliant with industry standard RFT electrical connector and cage EEPROM with serial ID functionality Auto-Negotiation follows IEEE 802.3u Clause 28 (1000BASE-T) and Cisco SGMII Spec. Compatible with the Cisco specification of SGMII interface. LCP-1250RJ3SR-S supports the SGMII interface without clock on MAC side Gigabit PHY device is integrated internally Internal PHY IC is configurable by host system software via SFP 2-wire-interface Description The LCP-1250RJ3SR-S is 3.3V copper small form-factor plug-able (SFP) transceiver. It offers full duplex 1000Mb/s Ethernet by transporting data over standard CAT 5 UTP cable (category 5 unshielded twisted pair), with RJ-45 connection. It takes signals from both CAT 5 UTP cable and the SFP SerDes interface. The system host (MAC) must enable SGMII auto-negotiation while LCP-1250RJ3SR-S is operated to setup the partner linking at one speed of 10/100/1000Mbps by 1000Base-T auto-negotiation. The Gigabit Ethernet SFP ports on host systems can work well plugging with both of Delta fiber SFP transceiver and Delta copper SFP transceiver, so there is no need of software to configure MAC on host system. At enhance, the software can configure the PHY device inner LCP-1250RJ3SR-S via SFP two-wire-interface.
