Abstract: The MAX3930 is designed for direct modulation of laser diodes at data rates up to 10.7Gbps. Operating from a single +5.0V or -5.2V power supply, the driver output can be DC-coupled to a common-anode laser diode, delivering a modulation current of 20mA to 100mA with an edge speed of 25ps. Proper design of the interfacing circuit between the laser and the driver is critical to control optical transmitter output performance at 10.7Gbps. This article establishes a simulation model for transient analysis and also addresses driver-to-laser interfacing.
