MAX7453 Evaluation Kit
Evluates:MAX7453
General Description
Features
♦ 5V Single-Supply Voltage
The MAX7453 evaluation kit (EV kit) evaluates the
MAX7453, a low-cost, triple-channel video reconstruc-
tion filter for S-video and CVBS video-signal applica-
tions. The EV kit operates from a 5V single-supply
voltage. The MAX7453 EV kit’s video input signals are
AC-coupled, while the video output signals can be
AC- or DC-coupled.
♦ Compatible with Standard Video Test Equipment
♦ Standard 75Ω Input/Output Terminations
♦ AC-Coupled Inputs
♦ AC- or DC-Coupled Outputs
♦ Surface-Mount Construction
♦ Fully Assembled and Tested

MAX7453 Evaluation Kit
Quick Start
Recommended Equipment
Before beginning, the following equipment is needed:
Detailed Description
The MAX7453 EV kit evaluates the MAX7453 triple-
channel video reconstruction filter and buffer. The EV
kit operates from a 5V single-supply voltage.
•
•
5V DC power supply (VCC)
The MAX7453 EV kit uses 0.1µF ceramic capacitors to
AC-couple the video input signals to the YIN and CIN
input pins of the MAX7453. The input capacitor stores a
DC level such that the outputs are clamped to the
appropriate DC voltage level. Both video input termi-
nals have a 75Ω termination to ground.
Video signal generator (e.g., Tektronix TG2000 or
similar)
•
Video measurement equipment (e.g., Tektronix
VM700A or similar)
Procedure
The MAX7453 EV kit video output signals can be DC- or
AC-coupled. At default, all jumpers (JU1–JU4) have no
shunts installed and each of the outputs are configured
to drive AC-coupled video loads. As configured, YOUT
and COUT each drive a 150Ω video (75Ω backmatch
resistor plus a standard 75Ω video cable). The compos-
ite video output CVOUT drives two 150Ω video loads.
The MAX7453 EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed.
1) Verify that no shunts are installed across jumpers
JU1–JU4 (AC-coupled outputs).
2) Connect the luma output from the video signal gen-
erator to the Y_IN BNC connector on the EV kit.

3) Connect the chroma output from the video signal
generator to the C_IN BNC connector on the EV kit.
The MAX7453 EV kit provides jumpers JU1–JU4 to con-
figure the video outputs to AC- or DC-coupling. At
default, each of the MAX7453’s AC-coupled outputs
include a 220µF series capacitor. To drive the output
video load directly, short the AC-coupling capacitor by
placing a shunt across the provided jumper. See Table
1 for shunt positions.
4) Connect the input of the video measurement equip-
ment to the Y_OUT, C_OUT, CV_OUT1, or
CV_OUT2 BNC connectors on the EV kit.
5) Connect the 5V supply to the VCC pad on the EV
kit. Connect the power-supply ground to the GND
pad on the EV kit.

(C_OUT, CV_OUT1, CV_OUT2, Y_OUT)
6) Set the signal generator for the desired video sig-
nal, such as multiburst.
7) Turn on the 5V DC power supply.

8) Analyze the video output signals with the video
measurement equipment.
