The CXB1558Q-Y is a high-speed monolithic Laser Driver/Current Switch with ECL input level. Open collector outputs are provided at the output pins (Q, Q) and have the capability of driving modulation current of 60mApp at a max. data rate of 2.0Gbps (NRZ). DRIVADJ and SDRIV inputs control the modulation current amplitude, and BIASADJ, SBIAS inputs control the bias current. Modulation and bias current can be controlled by either voltage or current through these pins. This device includes D-FF for duty cycle correction and Laser Shutdown function.
