MAX7453 Evaluation Kit
Quick Start
Recommended Equipment
Before beginning, the following equipment is needed:
? 5V DC power supply (VCC)
? Video signal generator (e.g., Tektronix TG2000 or
similar)
? Video measurement equipment (e.g., Tektronix
VM700A or similar)
Procedure
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.
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.
6) Set the signal generator for the desired video sig-
nal, such as multiburst.
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.
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 75 Ω termination to ground.
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 150 Ω video (75 Ω backmatch
resistor plus a standard 75 Ω video cable). The compos-
ite video output CVOUT drives two 150 Ω video loads.
JU1–JU4 Jumper Selection
(Output Coupling)
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.

(C_OUT, CV_OUT1, CV_OUT2, Y_OUT)
7) Turn on the 5V DC power supply.
8) Analyze the video output signals with the video
measurement equipment.
