155M Single Mode SFP Transceiver
Product Name: 155M Single Mode SFP TransceiverModel Number: BTRPlace of Origin: China155Mbps SM SFP transceiver (20km)Features:1) Single power supply: 3.3V2) Small form factor pluggable (SFP) MSA compatible3) LVPECL compatible signal interface4) Duplex LC connectorApplications:1) ATM switches and routers2) SONET/SDH switches infrastructure3) Fast Ethernet applicationAbsolute maximum ratings:Operating conditions:Transmitter: T=0 to+70°C, Vcc=3.13~3.47VReceiver: T=0 to + 70°C, Vcc=3.13~3.47V (+3.3V)Block diagram of transceiver:Pin assignment and function definitions:It is the responsibility of the system integrator to assure that no thermal, energy,or voltage hazard exists during the hot-plug-unplug sequence. It is also theresponsibility of the system integrator and end-user to minimize static electricityand the probability of ESD events by careful design.SFP transceiver electrical pad layout:Pin assignment:Functions:Notes:1. TX fault is an open collector output, which should be pulled up with a 4.7K~10Kresistor on the host board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicatesnormal operation; logic 1 indicates a laser fault. In the low state, theoutput will be pulled to less than 0.8V2. TX disable is an input that is used to shut down the transmitter optical output.It is pulled up within the module with a 4.7K~10K resistor. Its states are:Low (0~0.8V)Transmitter on (>0.8V,Undefined high (2.0~3.465V)Transmitter disabled openTransmitter disabled3. MOD-DEF 0, 1 and 2 are the module definition pins, should be pulled up with a4.7K~10K resistor on the host board. The pull-up voltage shall be VccT or VccR.MOD-DEF 0 is grounded by the module to indicate that the module is present. MOD-DEF1 is the clock line of two wire serial interfaces for serial ID. MOD-DEF 2 isthe data line of two wire serial interfaces for serial ID4. LOS is an open collector output, which should be pulled up with a 4.7K~10K resistoron the host board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicatesnormal operation; logic 1 indicates loss of signal. In the low state, the outputwill be pulled to less than 0.8V5. These are the differential receiver outputs. AC coupled 100 differential linesshould be terminated with 100 (differential), at the user serves6. These are the differential transmitter inputs: AC-coupled, differential lineswith 100 differential terminations inside the moduleRecommended host board supply filtering network:Example SFP host board schematic SFP:Mechanical:Order Information:
