MAX3741 Evaluation Kit
General Description
The MAX3741 evaluation kit (EV kit) is an assembled
demonstration board that provides complete optical
and electrical evaluation of the MAX3741 compact
VCSEL driver.
The EV kit has an electrical test section and an optical
test section. Electrically, the output of the evaluation
board is interfaced to an SMA connector, which can be
connected to a 50鈩?terminated oscilloscope. Optically,
the board can be configured to interface with a com-
mon-cathode VCSEL.

Quick Start
Electrical Evaluation
To ensure proper operation in the electrical configura-
tion, set up the evaluation board as follows:
1) To enable the outputs, connect TX_DISABLE to
GND by placing a shunt on JU1.
Note:
When performing the following resistance
checks, autoranging DMMs can forward bias the
on-chip ESD protection and cause inaccurate mea-
surements. To avoid this problem, manually set the
DMM to a high range.
