Maxim MAX3287 Manual

19-1961; Rev 0; 2/01
General Description
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-sur-
face emitting lasers (VCSELs) typically require a com-
mon-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 cur-
rent (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 com-
ponents to demonstrate a small, tight layout optimized
for optical evaluation.
