MAX3296 Longwave (Common Anode)
General Description
The MAX3296 longwave (LW) evaluation kit (EV kit) is
an assembled, surface-mount demonstration board that
provides easy optical and electrical evaluation of the
MAX3286 1.25Gbps laser driver or the MAX3296
2.5Gbps laser driver in the common-anode configura-
tion. This kit allows evaluation of the MAX3286/MAX3296
with long-wavelength laser diodes. Long-wavelength
(1310nm and greater) laser diodes are typically pack-
aged with their anode connected to a photodetector's
cathode.
Refer to the MAX3296EVKIT-SW for evaluation of the
MAX3286/MAX3296 with short-wavelength laser diodes
and VCSELs.
