Evaluation Kit for the MAX3287, MAX3288, MAX3297, MAX3298 Shortwave or VCSEL (Common Cathode)

All versions are Not Recommended for New Designs. See Ordering Information for recommended replacements.

The MAX3287 shortwave or VCSEL evaluation kit (EV kit) is an assembled, surface-mount demonstration board that allows easy optical and electrical evaluation of the MAX3287/MAX3288 1.25Gbps laser drivers or the MAX3297/MAX3298 2.5Gbps laser drivers in the common-cathode configuration. Short-wavelength laser diodes (wavelength < 980nm) and vertical cavity-surface emitting lasers (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.

When used with the MAX3287/MAX3297, the laser bias current regulates to keep a constant photodiode current (for shortwave laser diodes). When used with the MAX3288/MAX3298, the laser bias current is directly sensed and held constant.

This EV kit includes an extra blank circuit without components to demonstrate a small, tight layout optimized for optical evaluation.
