The MAX3296 shortwave or vertical cavity-surface emitting laser (VCSEL) evaluation kit (EV kit) is an assembled, surface-mount demonstration board that allows easy optical and electrical evaluation of the MAX3286 1.25Gbps laser driver or the MAX3296 2.5Gbps laser driver in the common-cathode configuration. Short-wavelength laser diodes (wavelength ≤ 980nm) and VCSELs typically require a common-cathode configuration. In the common-cathode configuration, the laser's cathode connects to ground and the laser is driven at its anode.
The MAX3296 shortwave or VCSEL EV kit regulates the laser bias current to keep a constant photodiode current or the kit directly senses the laser bias current and holds it constant.
Refer to the MAX3296EVKIT-LW for evaluation of the MAX3286/MAX3296 with long-wavelength laser diodes in the common-anode configuration.
