The MAX3975 evaluation kit (EV kit) is an assembled
demonstration board that provides complete optical
and electrical evaluation of the MAX3975 VCSEL driver.
The EV kit is composed of two independent sections,
one optical and one electrical, with a score line
between the sections for optional separation. The output
of the electrical section has an SMA connector that
can be connected to a 50Ω terminated oscilloscope.
The output of the optical section is configured for
attachment to the flex cable of a user-provided VCSEL
TOSA. Bias and modulation currents are manually set
with variable resistors.
Users can add the DS1862 controller IC with accompanying
hardware and software for closed-loop testing.
The DS1862 incorporates an automatic power control
(APC) feedback loop, extinction ratio control, and digital
diagnostics. Programming is accomplished through
an I²C-compatible interface, which can also be used to
access diagnostic functionality.
