MAX4135 Evaluation Kit
General Description
The MAX4135 evaluation kit (EV kit) simplifies evalua-
tion of the MAX4135 one-input, six-output distribution
amplifier. The EV kit circuit demonstrates the MAX4135
in a fixed gain of 2V/V. RF-style connectors (SMA) and
75Ω terminating resistors are included for video test-
equipment compatibility.
The EV kit comes with the MAX4135 installed, but can
also be used to evaluate the MAX4136, MAX4137, and
MAX4138 video distribution amplifiers. Contact Maxim
to order free samples.

Features
o 185MHz -3dB Bandwidth
o Outputs Can Be Independently Enabled and
Disabled
o Fully Assembled and Tested
Quick Start
The MAX4135 EV kit is fully assembled and tested.
Follow these steps to verify board operation. Do not
turn on the power supply until all connections are
completed.
1) The circuit requires supply voltages of ±5V. Connect
a +5V supply to the pad marked VCC. Connect a
-5V supply to the pad marked VEE. Connect the
power-supply ground to the pad marked GND.
2) Apply a signal in the +1.1V to -1.0V range to the
SMA connector marked IN.
3) Connect the output marked OUT1 to an oscilloscope
through a terminated 75Ω cable.
4) On DIP switch SW1, set the SEL1 switch to the on
position. Set all other switches to off.
5) Turn on the power supply and verify the output sig-
nal on the oscilloscope.
Detailed Description
Output Channel Selection
The MAX4135 provides TTL/CMOS-compatible, digital
control pins (SEL1–SEL6) to enable or disable each
amplifier output. When the SEL_ input is low, the ampli-
fier is enabled; when it is high, the amplifier is disabled.
The EV kit uses a DIP switch (SW1) to manually
enable/disable outputs. When a switch is on, the SEL_
pin is connected to ground, and the corresponding
amplifier is enabled. When a switch is off, the SEL_ pin
is connected to +5V through a 100kΩ pull-up resistor,
and the corresponding amplifier is disabled.
To use an external controller, set the desired SEL_
switch(es) to on and connect the external controller to
the pad(s) labeled SEL_.
