MAX3754/MAX3755 Evaluation Kits
General Description
Features
The MAX3754/MAX3755 evaluation kits (EV kits) simplify
evaluation of the MAX3754/MAX3755 quad-port bypass
circuit. The EV kits enable testing of all the devices’ func-
tions. SMA connectors and 50 terminations are provided
for all input and output ports to facilitate connection to stan-
dard high-speed test equipment. The MAX3754/MAX3755
EV kits are fully assembled and tested.
o SMA Connectors for All High-Speed Inputs and
Outputs
o On-Board 75 to 50 Impedance-Conversion
Networks for Interface with Standard Test
Equipment (MAX3754)
o Loss-of-Lock LED Indicator
o Jumpers to Enable Testing of All Functions
o Fully Assembled and Tested
