General Description
The MAX7443 evaluation kit (EV kit) evaluates the
MAX7443, a low-cost triple-channel video reconstruction
filter for composite and S-video applications. The EV kit
operates from a single 5V supply. The MAX7443 EV kit
can also be used to evaluate the MAX7444, a similar
device with a high-frequency boost option.
Features
♦ 5V Single Supply
♦ Compatible with Standard Video Test Equipment
♦ Surface-Mount Construction
♦ Fully Assembled and Tested
Quick Start
Recommended equipment
Before beginning, the following equipment is needed:
• Single 5V DC power supply
• Video signal generator (e.g., Tektronix TG 2000)
• Video measurement equipment (e.g., Tektronix
VM 700A)
Procedure
The MAX7443 EV kit is a fully assembled and tested
surface-mount board. Utilize the following steps to veri-
fy the board operation. Caution: Do not turn on the
power supply until all connections are completed:
1) Verify that there are shunts installed on JU1 and
JU3 (pins 1-2) and JU2 (pins 2-3).
2) Verify that there are shunts across jumpers JU4 and
JU5.
3) Connect the luma output from the video signal
generator to the YIN BNC connector on the EV kit.
4) Connect the chroma output from the video signal
generator to the CIN BNC connector on the EV kit.
5) Connect the input of the video measurement equip-
ment to the YOUT, COUT, or CVOUT BNC connec-
tors on the EV kit.
