General Description
The MAX7452 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board that contains
the MAX7452. The MAX7452 is a low-cost, high-perfor-
mance, complete front-end video-signal conditioner
with automatic gain control (AGC) and a user-
adjustable back-porch clamp. The device includes an
out-of-band noise filter, back-porch clamp, loss-of-sync
(LOS) detector, ±6dB of AGC, and an output buffer
capable of driving either a 150
video load or a high-
impedance load. These features optimize the video
signal quality for further video processing through a
crosspoint device or video decoder. The EV kit oper-
ates from a single +5V power supply.

Quick Start
Recommended Equipment
+5VDC power supply
Adjustable reference voltage (1V to 3V) or power sup-
ply
Video-signal generator (e.g., Tektronix TG-2000)
Video measurement equipment (e.g., Tektronix VM-
700A)
Procedure
The MAX7452 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) Verify that a shunt is installed across jumper JU1
(75
input termination).
2) Verify that a shunt is not installed across jumper
JU2 (75
output series termination).
3) Verify that a shunt is installed across pins 1 and 2 of
jumper JU3 (gain = 2).
4) Verify that a shunt is installed across pins 2 and 3 of
jumper JU4 (AGC enabled).
5) Connect the output of the video-signal generator to
the IN BNC connector on the MAX7452 EV kit.
