MAX9652 Evaluation Kit
Evluates:MAX9652
General Description
Features
♦ Single 3.3V Supply Operation
The MAX9652 evaluation kit (EV kit) is a fully assembled
and tested surface-mount PCB that contains the
MAX9652 triple-channel, video-filter amplifier for high-
definition television (HDTV) applications. The filter’s
passband is typically 42MHz. The video inputs on the
EV kit are AC-coupled; the video outputs can be AC- or
DC-coupled. In addition, the MAX9652 video inputs are
terminated with 75Ω and the video outputs have a 75Ω
back termination resistor. The EV kit operates from a
single 3.3V DC power supply.
♦ Output Buffer with a 2V/V Gain
♦ High-Definition Television Video Filter
♦ AC-Coupled Inputs
♦ Standard 75Ω Input/Output Terminations
♦ Surface-Mount Components
♦ Fully Assembled and Tested

MAX9652 Evaluation Kit
Quick Start
Recommended Equipment
Before beginning, the following equipment is needed:
Detailed Description of
Hardware
The MAX9652 EV kit is a fully assembled and tested
surface-mount PCB that contains the MAX9652 triple-
channel, video-filter amplifier and buffer for HDTV appli-
cations. The MAX9652 filter has 1dB passband out to
42MHz and 50dB attenuation at 109MHz. The
MAX9652 EV kit has three input channels to accept a
full set of component video input signals.
• 3.3V DC power supply (VDD) capable of 50mA
• Video signal generator (e.g., Tektronix TG-700 or similar)
• The appropriate video measurement equipment
(e.g., Tektronix VM5000)
Procedure
The MAX9652 EV kit is fully assembled and tested.
Follow the steps below to verify board operation:
The MAX9652 EV kit uses 0.1µF ceramic capacitors to
AC-couple the video input signals to the MAX9652. The
input capacitor stores a DC level such that the outputs
are clamped to the appropriate DC voltage level. All
video inputs have a 75Ω termination to ground. The
MAX9652 EV kit video outputs can be DC- or AC-cou-
pled. By default, 0Ω resistors are installed on R7, R8,
R9, and C4, C7, and C8 are open; each of the outputs
are configured to drive DC-coupled video loads. To
configure the outputs to drive the AC-coupled video
loads, remove R7, R8, and R9, and install the 220µF
capacitors on C4, C7, and C8.
1) Connect the outputs of the video signal generator to
the Y_INPUT, PB_INPUT, and PR_INPUT BNC con-
nectors on the MAX9652 EV kit.
2) Connect the Y_OUTPUT, PB_OUTPUT, AND
PR_OUTPUT BNC connectors on the EV kit to the
input of the video measurement equipment.
3) Connect the power-supply ground to the GND pad
on the EV kit.

4) Connect the 3.3V supply to the VDD pad on the EV kit.
5) Set the video signal generator for the desired video
input signals.
6) Turn on the power supply and enable the video sig-
nal generator.
7) Analyze the video output signal.
