MAX3781 Evaluation Kit
General Description
The MAX3781 evaluation kit (EV kit) is an assembled
demonstration board that provides easy evaluation of
the MAX3781 multiplexer/buffer. The MAX3781 EV kit
provides 100Ω differential output terminations on-
board, simplifying termination of unused outputs.
Features
o Fully Assembled and Tested
o +3.3V Operation
o On-Board Output Termination
o Easy Selection of Operating Modes

Note: Please indicate that you are using the MAX3781 when
contacting these component suppliers.
Quick Start
1) Apply +3.3V to the VCC pin. Connect power-supply
ground to the GND pin.
2) Shunt jumpers JU1 (SELA), JU2 (PD), and JU3
(SELB). Refer to Table 1 in the MAX3781 data sheet
for other configurations.
3) Apply up to 2.75Gbps differential data to LI2A±
(J17 and J18).
4) Remove R9 (differential termination resistor) from
the evaluation board.
5) Connect SOA± (J23 and J24) to a high-speed 50Ω
oscilloscope.
