File Size : 116 KB Manufacturer:MAXIM Description:Also added is an anti-rush circuitry, which is used to avoid over loading the laser diode during turn on. Typically AR or PD are connected, see Figure 2. In this case, the bias and modulation cur- rent are turned off, there will not be any voltage across the resistor connected to the back facet monitor diode photo de- tector. Therefore, without the anti-rush circuitry, the OPCL will adjust to increase the bias current, effectively setting the bias control voltage to its maximum, re- gardless of the setting of the voltage on the OPSET pin. Once the bias and modulation current is turned on again, the laser diode will be subject to the full bias current, and this may harm the laser diode. Therefore, an anti-rush circuitry has been provided, which sinks a current into the AR/PD pins when the bias and modulation current is turned off, SHDW = 1. This causes the AR/PD pins to be- come more negative than the reference voltage on the OPSET pin, and therefore causes the OPCL to turn down the con- trol for the bias current. This ensures a smooth turn on of the laser diode.
