Description

The LCP-1250RJ3SR-L 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 LCP-1250RJ3SR-L provides the SFP’s RX_LOS pin for the link indication of cable side, and also, 1000Base-T auto-negotiation is enabled at default over cable link.

The system host should disable 1000BASE-X auto-negotiation while LCP-1250RJ3SR-L is used.

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-L via SFP two-wire-interface. LCP-1250RJ3SR-L can also be configured to operate on SGMII mode, which provides with tri-speed mode, 10/100/1000 Mbps operation over 1.25 GHz serial interface, as long as the host system supports the SGMII interface in no-clock mode on SFP cage.

Applications

● Gigabit Ethernet over copper

● Switch to switch interface

● Switched backplane applications

● Gigabit Ethernet Interface of File Server

Performance

LCP-1250RJ3SR-L data link up to 100m on standard CAT 5 UTP
