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
10/100/1000 BASE-T operation in the host
system with SGMII interface (Default)
1000 BASE-T operation in the host system with
SerDes interface (To be configured)
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.
Applications
Gigabit Ethernet over copper
Switch to Switch interface
Switched backplane applications
File server interface
Performance
LCP-1250RJ3SR-S data link up to 100m on
standard CAT 5 UTP
