● Hot-pluggable SFP footprint

● 10/100/1000 BASE-T operation in the host systems with SGMII interface

● 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 IEEE 802.3z Clause 37 (1000BASE-X)

● Access to physical layer IC via 2-wire serial bus

● Compact RJ-45 connector assembly

Description

The LCP-1250RJ3SR is a 3.3V copper small form-factor pluggable (SFP) transceiver designed for Gigabit Ethernet over standard category 5 unshielded twisted pair (CAT 5 UTP) and provided with RJ-45 connection. It is also compatible with industry standard RFT electrical connector and cage.

Through LCP-1250RJ3SR, the 1000BASE-X fiber Auto-negotiation on the host board side is transparently converted to 1000BASE-T Auto-negotiation on the copper side. The host systems used to work with fiber SFPs will also work with LCP-1250RJ3SR copper SFPs, so there is no need to change MAC software.

The LCP-1250RJ3SR copper SFP also provides with tri-speed mode, 10/100/1000 Mbps operation over 1.25 GHz serial interfaces, as long as the host system supports the SGMII interface with no clocks.

Applications

● Gigabit Ethernet over copper

● Switch to switch interface

● Switched backplane applications

● File server interface

Performance

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