LCP-1250RJ3SRxx RoHS Compliant Copper Small Form Factor Pluggable (SFP) Transceiver for Gigabit Ethernet Features z Compatible with specifications for IEEE 802.3ab/Gigabit Ethernet z Compliant with MSA specifications for Small Form Factor Pluggable (SFP) Ports z Hot-pluggable SFP footprint z 1000 BASE-T operation in the host system with SerDes interface (Default for LCP-1250RJ3SR and LCP-1250RJ3SR-L) z 10/100/1000 BASE-T operation in the host system with SGMII interface (Default for LCP-1250RJ3SR-S) Description z Compliant with industry standard RFT electrical connector and cage The LCP-1250RJ3SRxx series are 3.3V copper small form-factor pluggable (SFP) transceivers. They offer full duplex 1000 Mb/s Ethernet by transporting data over CAT 5 UTP cable (category 5 unshielded twisted pair) with RJ-45 connector. The Gigabit Ethernet SFP ports on host systems can work well plugging with both of Delta fiber SFP transceivers and Delta copper SFP transceivers, so there is no need of software to configure MAC on host system. z EEPROM with serial ID functionality z Rx_LOS Indication (For LCP-1250RJ3SR-L) z Internal PHY IC is configurable by host system software via SFP 2-wire interface Application z Gigabit Ethernet over copper z Switch to Switch interface The LCP-1250RJ3SR-L provides the SFP’s Rx_LOS pin for the link indication of cable side, and also, 1000Base-T auto-negotiation is enabled at default over cable link. The system host (MAC) should disable 1000 BASE-X auto-negotiation while LCP-1250RJ3SR-L is used. z Switched backplane applications The system host (MAC) must enable SGMII auto-negotiation while LCP-1250RJ3SR-S is operated to setup the partner linking at one speed of 10/100/1000 Mbps by 1000Base-T auto-negotiation. z LCP-1250RJ3SRxx data link up to 100m on standard CAT 5 UTP. 1 DELTA ELECTRONICS, INC. z File server interface Performance Apr., 2009 Rev. 1.03 www.deltaww.com LCP-1250RJ3SRxx Absolute Maximum Ratings Parameter Storage Temperature Supply Voltage Symbol TS VCC Min. −40 0 Typ.

Apr., 2009 Rev. 1.03 www.deltaww.com LCP-1250RJ3SRxx Notes: 1. Tx Fault is not supported and tied to ground. 2. 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. 3. Low (0 – 0.8V): Transmitter on (>0.8, < 2.0V): Undefined High (2.0 – 3.465V): Transmitter Disabled Open: Transmitter Disabled 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 the indicator signal of 1000BASE-T link-up/ link-down status. HIGH indicates link-down while LOW indicates link-up. It should be pulled up with a 4.7K – 10KΩ resistor on the host board. This function is only available for LCP-1250RJ3SR-L. 5. VeeR and VeeT are internally connected. 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. 7. VccR and VccT are the receiver and transmitter power supplies, and they are internally connected. 8. TD+ and TD- are the transmitted differential inputs, and they are terminated with 100Ω differential load inside the module. 4 DELTA ELECTRONICS, INC.
