16) Look at the “eye” output on the oscilloscope. Laser
overshoot and ringing can be improved by appro-
priate selection of R17 and C18, as described in the
Designing the Laser-Compensation Filter Network
section of the MAX3286–MAX3289/MAX3296–
MAX3299 data sheet.
Evaluating the MAX3286
TQFP Package
The MAX3296EVKIT-LW board can easily be modified to
accommodate the MAX3286. Desolder and remove the
MAX3296 (the EV board ships with the MAX3296CHJ
installed), and replace it with the MAX3286CHJ (includ-
ed with the EV kit). No other circuit modifications are
necessary.
QFN Package
The MAX3296CGIL board can be modified to accom-
modate the MAX3286. Using a hot plate and a small
heating block to localize the heat underneath the part,
desolder and remove the MAX3296 (the EV board ships
with the MAX3296CGI installed), and replace it with the
MAX3286CGI (included with the EV kit). No other circuit
modifications are necessary.
