MAX9400 Evaluation Kit
The MAX9400 EV kit is a four-layer PC board with 50Ω
controlled-impedance input traces with 50Ω termination
(two parallel 100Ω resistors). All output signal traces
are also 50Ω controlled-impedance traces (with 49.9Ω
termination resistors).
The MAX9400 EV kit can be used to evaluate the
MAX9401–MAX9405 after modification. Table 4 lists on-
chip input and output termination to the corresponding
Maxim IC:

To evaluate the MAX9401, replace the MAX9400EHJ
with a MAX9401EHJ.
To evaluate the MAX9402, replace the MAX9400EHJ
with a MAX9402EHJ and remove output termination
resistors R1 to R8. The output is half-amplitude
compared to an open output because of the volt-
age-divider formed by the on-chip series 50Ω and
the 50Ω oscilloscope input.
To evaluate the MAX9403/MAX9404, replace the
MAX9400EHJ with a MAX9403EHJ/MAX9404EHJ
and remove input termination resistors R9 to R36.
To evaluate the MAX9405, replace the MAX9400EHJ
with a MAX9405EHJ and remove input and output
termination resistors R1 to R36. The output is half-
amplitude compared to an open output because of
the voltage-divider formed by the on-chip series
50Ω and the 50Ω oscilloscope input.
