FCOPPER-SFP-100 100BASE-TX Copper SFP Transceiver March 27, 2012 www.sixnet.com 1 FCOPPER-SFP-100 Product Overview The electrical Small Form Factor Pluggable (SFP) transceiver module is specifically designed for converting 100BASE-FX NRZI port interface to 10/100BASE-TX interface with RJ45 connector. The transceiver module is compliant with the SFP MultiSource Agreement (MSA) and IEEE802.3u. With hot pluggability, the module offers a flexible and easy way to be installed into SFP MSA compliant ports at any time without the interruption of the host equipment’s operating online. The Copper SFP transceivers use an integrated RJ-45 connector with transformer and PHY IC.

All Rights Reserved. 2 FCOPPER-SFP-100 Block Diagram The transceiver is fundamentally consisted by three parts: RJ45+Magnetics, PHY IC and EEPROM. The transceiver module can be turned on by setting TX_DISABLE = LOW and can be reset by setting TX_DISABLE =High or OPEN. TX_FAULT is not supported in Copper products and always be connected to ground. LOS (Loss of Signal) detection is optional. For accessing the serial identification information, an EEPORM is used to store the required data via the 2-wire serial CMOS EEPROM protocol.

Its states are: Low (0 – 0.8V): transceiver module on. (>0.8, < 2.0V): Undefined. High (2.0 – 3.465V): transceiver module disabled. Open: transceiver module disabled. 3.Mod-Def 0,1,2, are the module definition pins, which should be pulled up with a 4.7K - 10K 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 is the clock line of two-wire serial interface for serial ID. Mod-Def 2 is the data line of two-wire serial interface for serial ID. 4.Rate select is not required for connection. 5.RX_LOS (Loss of Signal): LVTTL compatible with a maximum voltage of 3.3V 6.VeeR and VeeT may be internally connected within the SFP module. 7.RD-/+, the differential receiver outputs, are AC coupled 100Ω differential lines which should be terminated with 100 L differential at the user SerDes. The AC coupling is done inside the module, thus not required on the host board. The voltage swing on these lines will be between 370 and 2000 mV differential (185 mV- 1000 mV single ended) when properly terminated. 8.VccR and VccT are the receiver and transmitter power supplies defined as 3.3V ±5% at the SFP connector pin. Maximum supply current is 385 mA. Recommended host board power supply filtering is shown below. Inductors with DC resistance of less than 1 L should be used in order to maintain the required voltage at the SFP input pin with 3.3V supply voltage. When the recommended supply filtering network is used, hot plugging of the SFP transceiver module will result in an inrush current of no more than 30 mA greater than the steady state value. VccR and VccT may be internally connected within the SFP transceiver module. 9.TD-/+, the differential transmitter inputs, are AC-coupled differential lines with 100L differential termination inside the module. The AC coupling is done inside the module, thus not required on the host board. The inputs will accept differential swings of 500 – 2400mV (250 mV - 1200 mV single ended) though it is recommended that values between 500 and 1200mV differential (250 – 600mV single ended) be used for best EMI performance.
