Note1. TX Fault is open collector/drain output which should be pulled up externally with a 4.7K 10KΩresistor on the host board to supply <VccT+0.3V or VccR+0.3V. When high, this output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to <0.8V. Note2. TX Disable input is used to shut down the laser output per the state table below. It is pulled up within the module with a 4.7 10K resistor. Low (0 0.8V): Transmitter on ( >0.8V, < 2V): Undefined High (2.0 VccT): Transmitter Disabled Open: Transmitter Disabled Note3. Mod-Def 0, 1, 2. These are the module definition pins. They should be pulled up with a 4.7-10KΩresistor on the hostboard to supply less than VccT+0.3V or VccR+0.3V. Mod-Def 0 is grounded by the module to indicate that the module is present. Mod-Def 1 is clock line of two wire serial interface for optional serial ID. Mod-Def 2 is data line of two wire serial interface for optional serial ID. Note4. LOS (Loss of signal) is an open collector/drain output which should be pulled up externally with a 4.7 10K resistor on the host board to supply <VccT+0.3V or VccR+0.3V. When high, this output indicates the received optical power is below the worst case receiver sensitivity (as defined by the standard in use). Low indicates normal operation. In the low state, the output will be pulled to <0.8V. Note5. RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be terminated with 100Ω differential at the user SERDES. The AC coupling is done inside the module and is thus not required on the host board. Note6. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V±5% at the SFP connector pin. The in-rush current will typically be no more than 30mA above steady state supply current after 500ns. Note7. TD-/+: These are the differential transmitter inputs. They are AC coupled differential lines with 100Ω differential termination inside the module. The AC coupling is done inside the module and is thus not required on host board. www.wavesplitter.com Page 10 of 14
Block Diagram Required Host Board Components The MSA power supply noise rejection filter is required on the host PCB to meet data sheet performance. The MSA filter incorporates an inductor which should be rated 400mADC and 1Ωserial resistance or better. It should not be replaced with a ferrite. The required filter is illustrated in Figure 3. The MSA also specifies that 4.7K to 10KΩ pull-up resistors for TX_FAULT, LOS, and MOD_DEF0,1,2 are required on the host PCB. Figure is the suggested transceiver/host interface. www.wavesplitter.com Page 11 of 14
