RoHS Compliant Copper Small Form-factor Pluggable (SFP)
Transceiver for Gigabit Ethernet with Rx-Los Indicator
Description
The LCP-1250RJ3SR-L is a 3.3V
copper small form-factor pluggable (SFP)
transceiver. It offers full duplex 1000 Mb/s
Ethernet by transporting data over 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-nego-
-tiation is enabled at default over cable link.
The system host should disable 1000
BASE-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 fible 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-inter- face. LCP-1250RJ3SR-L can also
be operate on SGMII mode, which 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 clock
mode on SFP cage. The SGMII interface without
clock is selected by setting HWCFG_MODE[3:0]
bits to ‘0100’.
