Description

The CXB1549Q 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 max. data rate of 1.25Gbps (Min.). Along with the modulation current generator there is the laser diode bias generator which has capacity of sourcing up to 60mA (Bias).
