Description
Applications
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.
z Gigabit Ethernet over copper
z Switch to switch interface
z Switched backplane applications
z File server interface
Performance
z LCP-1250RJ3SR data link up to 100m on
standard CAT 5 UTP

Notes:
1. This part supports the 1000 Base-T with SerDes interface by default. It can operate in 10/100/1000
Base-T with SGMII interface by reconfiguration of the PHY within the SFP.
2. This part uses the SFP’s Rx-Los pin for link indication and 1000 Base-T auto-negotiation should be
disabling on the host system. It can operate in 10/100/1000 Base-T with SGMII interface by
reconfiguration of the PHY within the SFP.
3. This part supports the 10/100/1000 Base-T with SGMII interface by default.

TX Fault is not supported and tied to ground.
TX disable is an input that is used to reset the chip of Gigabit Ethernet PHY inside the copper SFP. It is pulled
up within the module with a 4.7 – 10 K Ω resistor.

These are the module definition pins.
They should be pulled up with a 4.7K – 10KΩ resistor on the host board.
The pull-up voltage shall be VccT or VccR. MOD-DEF 0 is grounded in the module to indicate that the module is
present.
MOD-DEF 1 and MOD-DEF 2 are the clock and data lines of the two-wire serial interface, respectively.
4)
LOS (Loss of Signal) is not available and tied to ground.
5)
VeeR and VeeT are internally connected within the copper SFP.
6)
RD+ and RD- are the received differential outputs, and they are AC-coupled 100Ω differential lines that should be
terminated with 100Ω (differential) at user’s SERDES.
The AC coupling is done inside the copper SFP and thus
not required on the host board. The differential voltage swing will be between 250mV and 625 mV, while properly
terminated.
7)
VccR and VccT are the receiver and transmitter power supplies, and they are internally connected within the
copper SFP. The power rail is defined as 3.3V ±5% at the SFP connector pin.
