LCP-1250RJ3SR-S

Description

The LCP-1250RJ3SR-S is a 3.3V copper small form-factor pluggable (SFP) transceiver. It offers full duplex 1000M/s Ethernet by transporting data over standard CAT 5 UTP cable（category 5 unshielded twisted pair, with R J-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 oper ated to setup the partner linking at one speed of 10/100/1000 Mbps by 1000Base-T auto-negot iation.

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. The SGMII interface without clock is selected by setting HWCFG_MODE[3:0] bits to ‘1100’ or ‘1000’.

Features

Compliant with specifications for IEEE 802.3z/Gigabit Ethernet

Compliant with MSA specifications for Small Form Factor Pluggable （SFP）Ports Hot-pluggable SFP footprint
