(SCP6868-GL) - 4 / 20 - Specification : TS-S03D072A April , 2003 Note 1) Tx Fault is an open collector output that shall be pulled up with a 4.7k - 10kΩ resistor on the host board. Pull up voltage between 2.0V and VccT+0.3V. When high, output indicates a laser fault of some kind. Low indicates normal operation. Tx Fault is asserted when bias current of laser exceeds the factory-calibrated threshold level. The laser output is not turned off in case of Tx Fault. 2) Tx Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a 4.7kΩ resistor. 3) Mod-Def 0,1,2. 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. Mod-Def 0 indicates 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) LOS (Loss of Signal) is an open collector output that shall be pulled up with a 4.7k - 10kΩ resistor. Pull up voltage between 2.0V and VccR+0.3V. Low indicates normal operation. 5) 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. 6) 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 the host board. Figure 4.
