CXB1818Q Laser Diode Driver Description The CXB1818Q is a high-speed monolithic Laser Diode Driver/Current Switch with ECL/PECL input level. Open collector outputs are provided at the output pins (Q, QBX) and have the capacity of driving modulation current of 50mAp-p at a maximum data rate of 622Mbps. Along with the modulation current generator there is the laser diode bias current generator which has capacity of sourcing up to 60mA (Bias). The laser diode bias current can be controlled by either a voltage or current into the bias adjust pin (BiasAdj) and the bias set pin (SBias), depending on how these pins are configured. Control of the bias current is achieved through the APC (Automatic Power Control) circuit.
